▎ 摘　　要

In this study we investigate the Zitterbewegunq (ZB) (jitter motion) effect in a thin film formed by graphene grown on a boron nitride substrate in the presence of a terahertz pump pulse, where the conduction electrons are described on the basis of the long-wavelength effective Hamiltonian in the case of low temperatures. An analytical expression is obtained which describes the current induced by the motion of the wave packet of electrons. The dipole radiation is calculated.
