Photocurrent in a two-dimensional ribbon with the conic electron spectrum
Abstract
The strips of graphene or 2D HgTe with the conic electron spectrum illuminated by interband radiation are studied in the assumption of classical carriers motion. Linearly polarized radiation produces optical orientation of electron momenta. The asymmetry of edges together with the radiation polarization leads to electric current along the strip. The cases of narrow and wide strip with respect to the mean free path are considered. Besides, the edge photocurrent is investigated in a wide strip, one of edge of which is illuminated. We show that interelectron collisions play an important role by violating e-h symmetry that provides the overall current.
