TL;DR: Calculations of the conductivity and resistivity of an electron-hole many-layer system under the influence of electromagnetic waves whose frequencies are high compared to the collision frequencies and whose wavelengths are longCompared to the Bohr (Debye) radius are carried out.
Abstract: By using a method which employs a kinetic description and linear-response theory, we calculated the conductivity of electron-ion many-layer system (type-I superlattices) in the high-frequency and long-wavelength limits. Here electromagnetic radiation is taken to be a homogeneous, oscillating electric field. Our calculation takes into account all contributions in lowest order of the plasma parameter ${r}_{s}$. Expressions for frequency-dependent scattering time and effective mass have been numerically obtained. Asymptotic limits for small and large frequencies are analytically derived.
