UNAM researchers show photocurrent generation in metallic layered nanomaterials

Photocurrent generation is a key process in optoelectronics. Typically semiconducting materials are used as the non-equilibrium charge carriers created by optical excitation can efficiently be separated to create electric current. However, this process doesn't occur in metallic materials besides a few exceptions as the number of intrinsic charge carriers are far greater than the photoexcited [...]
