Abstract:
The electron diffusion coefficient and the electrical conductivity of a graphene bilayer in an external electric field with a strength vector directed along the graphene sheet are calculated theoretically. The evolution of the electron system is simulated using the Boltzmann kinetic equation in the relaxation-time semi-classical approximation. Analytic expressions are obtained for the electron diffusion coefficient and the electrical conductivity, and the nonlinear dependences of these quantities on the electric field are established. The dependences of these quantities on the control electrostatic potential between graphene layers are analyzed.
