The high harmonic generation оn superlattices based on graphene at the presence of a uniform electric field

The high harmonic generation on superlattices based on graphene under the influence of а variable and a uniform electric fields is considered. Intensities vectors of these fields are directed along superlattices axis. The electron system superlattices based on graphene is considered using the kinetic Boltzman equation with a constant relaxation time. The dependence of the amplitude of the high harmonic from fields characteristics is investigated.
