Description	Monte Carlo simulations are employed to calculate terahertz conductivity of charge carriers in a potential with periodic modulation on the nanoscale. The modulation gives rise to two characteristic features in the conductivity spectra: a Drude peak owing to charge carriers with kinetic energy exceeding the modulation depth, and resonance due to charge carriers localized around potentialminima. Both peaks shift in an appliedmagnetic field.We discuss the relationship between the modulation potential and the positions and strengths of the resonances. We also analyze the role of depolarization fields which are responsible for the difference between local and effective conductivity.
