Our research is focused on electronic and optical properties of two-dimensional materials, topological insulators and of nanostructured semiconductor. The physics of two dimensionnal materials such as graphene, semiconducting transition metal dichalcogenides, and of\u00a0 van der Waals magnets are the most representative directions in our recent studies. The effects of interactions, electron-phonon, magnon-phonon and electron-electron as well as spin-dependent phenomena are of particular interest. Spatially resolved optical spectroscopy, from microwaves up to visible spectral range, and electronic transport, both in combination with applications of high magnetic fields, low temperatures and\/or of high hydrostatic pressure are our main experimental tools. The techniques of spatially resolved magneto-optical spectroscopy, in particular low energy Raman scattering in fields up to 31T and with hydrostatic pressure up to 20 GPa, are unique experimental methods recently developed in the lab.<\/p>\n
Numerous collaboration links and projects are vital for our research activity. Those include recent common works with research teams from IN\u00e9el- and LPMMC-Grenoble, LPS-Orsay, C2N-Saclay, Universities of Montpellier, Marseille, Prague, Munchen, Warsaw, Wroclaw, Geneva, Oxford and Manchester, IPPAS-Warsaw and Helmholtz-Zentrum, Dresden.<\/p>\n<\/div>\n

Since then, we keep on discovering new van der Waals magnets, representative of most magnetic orders found in bulk systems (ferromagnets, antiferromagnets, ferrimagnets, non-colinear magnets, etc …) with the possibility to thin them down to the monolayer and investigate their magnetic properties down to the 2D limit. We are particularly interested in the properties of s<\/span>pin waves (magnons) and and of lattice vibrations (phonons) which are intrinsically coupled through magnetoelastic interaction. This coupling is always effective but its effects are strongly enhanced when excitations from the magnetic and from the elastic systems are tuned in resonance. In this case, excitations from the coupled systems are mixed excitations involving phonons and magnons and are called magnon-polarons (see Figure for zig-zag antiferromagnet FePS3<\/sub>). Such resonances can be achieved by tuning external parameters such as a magnetic field or hydrostatic pressure. At the resonance,\u00a0 the modes display a characteristic avoided crossing and the splitting energy between the two modes is a direct measurement of the magneto-elastic interaction.<\/span><\/p>\nFigure: Low temperature magneto-Raman scattering of bulk FePS3<\/sub> showing the magnon excitation (M) splitting when B is applied and experiencing a pronounced coupling with the P3 phonon mode.<\/span><\/p>\n[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_4,3_4″ _builder_version=”4.27.4″ _module_preset=”default” module_alignment=”center” custom_margin=”|859px||auto||” global_colors_info=”{}”][et_pb_column type=”1_4″ _builder_version=”4.25.2″ _module_preset=”default” global_colors_info=”{}”][et_pb_image src=”https:\/\/lncmi.cnrs.fr\/wp-content\/uploads\/2025\/02\/IX-1.jpg” title_text=”IX” _builder_version=”4.27.4″ _module_preset=”default” width=”352px” height=”330px” custom_margin=”|-117px||||” global_colors_info=”{}” max_width__hover_enabled=”off|desktop” max_height__hover_enabled=”off|desktop”][\/et_pb_image][\/et_pb_column][et_pb_column type=”3_4″ _builder_version=”4.25.2″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.27.4″ _module_preset=”default” min_height=”116.8px” custom_padding=”0px|||71px||” global_colors_info=”{}”]<\/p>\n
2D semiconductors and their heterostructures<\/strong><\/p>\nSemiconducting transition metal dichalcogenides (S-TMD) such as MoSe2<\/sub>, MoSe2<\/sub>, WSe2, WS2<\/sub>, MoTe2<\/sub>, are van der Waals semiconductors that can be thinned down to the monolayer limit. In the monolayer form, they show fascinating properties\u00a0 such as direct band gap, valley selective circular dichroism,\u00a0 a very rich exciton physics sensitive to screening effects and to doping showing charged exciton complexes. They can be stacked on top of one another to form heterobilayers hosting spatially indirect excitons and possibly affected by the moir\u00e9 potential. We use high magnetic fields to explore the physics of these systems mainly based on the determination of their g-factors, diamagnetic shift representative of the spatial extent of the exciton, reduced mass etc … based on their emission spectrum. We also use high magnetic to brighten dark excitons and obtain information concerning the electronic band structure.<\/p>\nFigure: Low temperature magneto-photoluminescence from interlayer excitons in a MoSe2<\/sub>\/WSe2<\/sub> heterobilayer.<\/p>\n[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_4,3_4″ _builder_version=”4.25.2″ _module_preset=”default” module_alignment=”center” global_colors_info=”{}”][et_pb_column type=”1_4″ _builder_version=”4.25.2″ _module_preset=”default” global_colors_info=”{}”][et_pb_image src=”https:\/\/lncmi.cnrs.fr\/wp-content\/uploads\/2025\/05\/Topo.png” title_text=”Topo” src_last_edited=”off|desktop” _builder_version=”4.27.4″ _module_preset=”default” width=”300px” height=”300px” global_colors_info=”{}” max_width__hover_enabled=”off|desktop” max_height__hover_enabled=”off|desktop” src__hover_enabled=”off|desktop”][\/et_pb_image][\/et_pb_column][et_pb_column type=”3_4″ _builder_version=”4.25.2″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.27.4″ _module_preset=”default” custom_padding=”|||72px||” global_colors_info=”{}”]<\/p>\n
Topological insulators<\/strong><\/p>\nThe application of mathematical topology\u2014originally developed for abstract spaces\u2014to the study of electronic bands in crystalline solids has opened an entirely new research direction in condensed matter physics. This new perspective has led to a series of theoretical predictions and, importantly, experimental discoveries that revealed band-structure features and associated phenomena previously unnoticed when solids were classified solely by their electronic energy spectra. While the physical properties of topologically non-trivial materials vary, they share key characteristics\u2014most notably, the presence of gapless electronic phases. Examples include conical bands on the surface of topological insulators and bulk Dirac or Weyl cones in the band structures of semimetals. As a result, topological materials are natural candidates for optical and magneto-optical spectroscopy studies in the THz and infrared spectral ranges. Conducting such experiments, particularly in the Landau quantization regime (Landau level spectroscopy), provides us with valuable insights into the electronic band structures of these intriguing materials. The high-magnetic-field facility at LNCMI-CNRS in Grenoble has been instrumental in studying various topological systems, including Dirac and Weyl semimetals (Cd\u2083As\u2082, TaP, TaAs, HgCdTe), nodal-line and nodal-loop systems (NbAs\u2082, BaNiS\u2082), or topological insulators (Bi\u2082Se\u2083, PbSnSe, Bi\u2082Te\u2083, MnBi2<\/sub>Te4<\/sub>, Sb\u2082Te\u2083).<\/span><\/p>\n<\/strong><\/p>\n<\/strong><\/p>\n[\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ module_id=”techniques” _builder_version=”4.27.2″ _module_preset=”default” min_height=”422.8px” custom_padding=”||0px|||” locked=”off” global_colors_info=”{}”][et_pb_row _builder_version=”4.26.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.26.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_text module_id=”techniques” _builder_version=”4.27.0″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n

We have developped experimental set-ups for spatially resolved optical spectroscopy in the visible and NIR range of energy based on free beam optics. A microscope objective focuses excitation light on a ~1 \u00b5m spot and is used to collect reflected\/scattered\/emitted signals. Light is then sent using metalic mirors to a grating spectrometer equipped with a nitrogene cooled CCD. We use laser wavelength of 325 nm – 395 nm – 473 nm – 515 nm – 633 nm – Ti:Sapp laser, a supercontinuum laser, or white light excitation. Time-resolved experiments are possible either with avalanche photodiodes or with a streak camera.<\/p>\n

The setup for THz\/infrared magneto-spectroscopy at the LNCMI in Grenoble is based on the conventional and robust Fourier-transform technique. It allows us to probe the optical response (transmission, reflectivity, Faraday rotation) of bulk and thin-layer samples in various configurations (Faraday and Voigt configurations possible), up to high magnetic field (currently 37T), in a broad range of photon energies (1-1000 meV) and temperatures (2-300 K @ B<18T). Experiments using a circularly polarized radiation can be realized in the mid-infrared range. <\/span><\/p>\n[\/et_pb_toggle][et_pb_toggle title=”Extreme conditions” _builder_version=”4.27.4″ _module_preset=”default” locked=”off” global_colors_info=”{}”]<\/p>\n
We generate extreme experimental conditions of<\/p>\n

– high hydrostatic pressure up to P=20 GPa using a diamond anvil cell and a long working distance microscope objective.<\/p>\n

<\/strong><\/p>\n
In 2017, scientists have succeeded in isolating a monolayer from a van der Waals magnet, CrI3<\/sub>,\u00a0 and have demonstrated that the magnetic properties persits in monolayers [<\/span>Hwang17<\/span><\/a>]. Since then, we keep on discovering new van der Waals magnets, representative of most magnetic orders found in bulk systems (ferromagnets, antiferromagnets, ferrimagnets, non-colinear magnets, etc …) with the possibility to thin them down to the monolayer and investigate their magnetic properties down to the 2D limit. We are particularly interested in the properties of s<\/span>pin waves (magnons) and and of lattice vibrations (phonons) which are intrinsically coupled through magnetoelastic interaction. This coupling is always effective but its effects are strongly enhanced when excitations from the magnetic and from the elastic systems are tuned in resonance. In this case, excitations from the coupled systems are mixed excitations involving phonons and magnons and are called magnon-polarons (see Figure for zig-zag antiferromagnet FePS3<\/sub>). Such resonances can be achieved by tuning external parameters such as a magnetic field or hydrostatic pressure. At the resonance,\u00a0 the modes display a characteristic avoided crossing and the splitting energy between the two modes is a direct measurement of the magneto-elastic interaction.<\/span><\/p>\n

2D semiconductors and their heterostructures<\/strong><\/p>\n
Semiconducting transition metal dichalcogenides (S-TMD) such as MoSe2<\/sub>, MoSe2<\/sub>, WSe2, WS2<\/sub>, MoTe2<\/sub>, are van der Waals semiconductors that can be thinned down to the monolayer limit. In the monolayer form, they show fascinating properties\u00a0 such as direct band gap, valley selective circular dichroism,\u00a0 a very rich exciton physics sensitive to screening effects and to doping showing charged exciton complexes. They can be stacked on top of one another to form heterobilayers hosting spatially indirect excitons and possibly affected by the moir\u00e9 potential. We use high magnetic fields to explore the physics of these systems mainly based on the determination of their g-factors, diamagnetic shift representative of the spatial extent of the exciton, reduced mass etc … based on their emission spectrum. We also use high magnetic to brighten dark excitons and obtain information concerning the electronic band structure.<\/p>\n

Topological insulators<\/strong><\/p>\n
The application of mathematical topology\u2014originally developed for abstract spaces\u2014to the study of electronic bands in crystalline solids has opened an entirely new research direction in condensed matter physics. This new perspective has led to a series of theoretical predictions and, importantly, experimental discoveries that revealed band-structure features and associated phenomena previously unnoticed when solids were classified solely by their electronic energy spectra. While the physical properties of topologically non-trivial materials vary, they share key characteristics\u2014most notably, the presence of gapless electronic phases. Examples include conical bands on the surface of topological insulators and bulk Dirac or Weyl cones in the band structures of semimetals. As a result, topological materials are natural candidates for optical and magneto-optical spectroscopy studies in the THz and infrared spectral ranges. Conducting such experiments, particularly in the Landau quantization regime (Landau level spectroscopy), provides us with valuable insights into the electronic band structures of these intriguing materials. The high-magnetic-field facility at LNCMI-CNRS in Grenoble has been instrumental in studying various topological systems, including Dirac and Weyl semimetals (Cd\u2083As\u2082, TaP, TaAs, HgCdTe), nodal-line and nodal-loop systems (NbAs\u2082, BaNiS\u2082), or topological insulators (Bi\u2082Se\u2083, PbSnSe, Bi\u2082Te\u2083, MnBi2<\/sub>Te4<\/sub>, Sb\u2082Te\u2083).<\/span><\/p>\n

A microscope objective focuses excitation light on a ~1 \u00b5m spot and is used to collect reflected\/scattered\/emitted signals. Light is then sent using metalic mirors to a grating spectrometer equipped with a nitrogene cooled CCD. We use laser wavelength of 325 nm – 395 nm – 473 nm – 515 nm – 633 nm – Ti:Sapp laser, a supercontinuum laser, or white light excitation. Time-resolved experiments are possible either with avalanche photodiodes or with a streak camera.<\/p>\n

The setup for THz\/infrared magneto-spectroscopy at the LNCMI in Grenoble is based on the conventional and robust Fourier-transform technique. It allows us to probe the optical response (transmission, reflectivity, Faraday rotation) of bulk and thin-layer samples in various configurations (Faraday and Voigt configurations possible), up to high magnetic field (currently 37T), in a broad range of photon energies (1-1000 meV) and temperatures (2-300 K @ B<18T). Experiments using a circularly polarized radiation can be realized in the mid-infrared range. <\/span><\/p>\n

We generate extreme experimental conditions of<\/p>\n
– low temperature using cryostats with liquid helium. Our set-ups operate under helium exchange gas between T = 1.2 K and 300 K.
– high magnetic fields using our superconducting magnets (14 T for visible otics, 16 T for Infrared spectrosocopy) or the resistive magnets of LNCMI delivering up to 37 T (limited to 31 T for visible spectroscopy)
– high hydrostatic pressure up to P=20 GPa using a diamond anvil cell and a long working distance microscope objective.<\/p>\nI. Breslavetz et al., Rev. of Scien. Instr. 92, 123909 (2021)<\/a><\/p>\n
