Title: | Analytic solution for electrons and holes in graphene under electromagnetic waves: Gap appearance and nonlinear effects |
Authors: | Naumis, GG López-Rodríguez, FJ |
Issue Date: | 2008 |
Abstract: | We find the exact solution of graphene carriers dynamics under electromagnetic radiation. To obtain the solution of the corresponding Dirac equation, we combine Floquet theory with a trial solution. Then the energy spectrum is obtained without using any approximation. We also prove that the energy spectrum presents a gap opening, which depends on the radiation frequency and electric wave intensity, whereas the current shows a strongly nonlinear behavior. |
