In this talk I present our study of shift current(SC) response in twisted bi-layer(TBG) and twisted tri-layer graphene (TTG). We found that TTG as an ideal platform for the observation of a highly controllable SC conductivity in the THz/infrared frequency regime. At small angle it is possible to promotes the far-infrared THz SC up to… Read More
The interplay between magnetism and light absorption holds promise for novel photovoltaic technologies, and recent research explores this connection within the unique structure of graphene. Yuncheng Mao and Claudio Attaccalite, both from CNRS/Aix-Marseille Université, investigate how magnetic fields influence the bulk photovoltaic effect in Bernal bilayer graphene, a material formed by stacking two graphene layers….
