Monte Carlo simulation of 2D TASER

摘要

A possibility to develop the so called TASER (Terahertz-Amplification-by-the-Stimulated-Emission-of-Radiation) by using two-dimensional (2D) electron transport in quantum well (QW) structures is investigated by Monte Carlo simulation of the optical-phonon-emission assisted transit-time resonance (OPTTR) of 2D electrons in momentum space under the low lattice temperature. A considerable extension of the frequency region for THz radiation generation (upto 5 times) when going from 3D- to 2D-case is predicted.
