Abstract

We report a study of the role of electron scattering at acoustic and polar optic phonons for Bloch gain of a terahertz radiation in semiconductor superlattices of different miniband widths. A three-dimensional Monte Carlo method was employed to calculate the dynamic mobility of miniband electrons in GaAs/AlAs superlattices subject to both static and high-frequency fields at low temperature (4 ...
