Abstract: Using first-principles calculations, we investigate the photogalvanic effect (PGE) in photodetectors based on tungsten telluride/molybdenum telluride (WTe2/MoTe2) heterostructures. Our calculations reveal that the photocurrent generated by the PGE exhibits a highly asymmetric response along the… read more here.
