Phase transition induced carrier mass enhancement in a 2D perovskite
Organic-inorganic halide perovskites have become the “next big thing” in emerging semiconductor materials, with their unprecedented rapid development and...
High magnetic fields probe multiexciton states in organic materials
Intermolecular coupling plays a key role in charge transport and excited-state dynamics in organic systems. A key example of the influence of intermolecular...
Broadband spectroscopy at extreme magnetic fields: First results
Magnetic fields exceeding 100 T can be obtained only by semi-destructive methods. In one approach, the magnetic field is generated by a single-turn coil,...
