Magnetoabsorption of elliptically polarized electromagnetic radiation by graphene: The relaxation-time approximation and Monte Carlo method

Abstract

It has been shown that the linewidth of cyclotron absorption in band gap graphene is nonzero even in the absence of electron scattering. The functional temperature dependence of the cyclotron absorp tion linewidth, which is applicable to band gap graphene in the absence of collisions, has been analytically determined. The power of the elliptically polarized electromagnetic wave absorbed by graphene in the pres ence of a dc magnetic field has been numerically calculated. The Monte Carlo numerical experiment has confirmed the analytical calculations based on the Boltzmann equation.
