Abstract:
The electromagnetic radiation of electrons in the corrugated graphene has been studied in the presence of a transport electric current in the ballistic regime. We considered here the impact of ripples in monolayer graphene on its electromagnetic properties. Electromagnetic radiation was actually calculated with a use of the standard electromagnetic theory. Two cases: those of regular and random structures were analyzed. The nonlinear relationship between the random height function $h(x,y)$ and the gauge field is shown to create a central radiation frequency distribution peak.
Keywords:
dipole approximation, graphene, ripples, improper, gauge field.
