Abstract: With a THz electric field,an electron in a one-dimensional would be located.Using a relaxation-time approximation for scattering,the density matrix equation of motion within a single miniband is solved.The author obtained the electronic response by calculating the dipole moment,and analyzed the power dissipated.The collisions are crucial in eliminating transients.The optical properties of superlattice depend on the dynamic localization of electrons.

Key words: superlattice, nonlinear response, THz electric field, power dissipated
