Abstract
We investigate the transmission of divergent electron beams through a succession of barriers in graphene, in order to search for possible applications of these structures in nanoelectronics. We show that the periodically gated structures are very sensitive to the variation of the external electric field, such that they can be used to modulate the transmission coefficient of electrons at oblique incidence by a slight change in the potential energy of the barriers and to steer electron beams.
