摘要：

In this study we investigate the propagation of extremely short optical pulses in a thin film formed by a graphene grown on a boron nitride substrate. Conduction electrons of the system are described on the basis of the long-wavelength effective Hamiltonian in the case of low temperatures; the electromagnetic field being taken into account within the framework of the classical Maxwell equations. The time evolution of the pulse's shape for different speeds and maximum amplitudes of an extremely short pulse is analyzed. (C) 2013 Elsevier B.V. All rights reserved.
