Terahertz instability of optical phonons interacting with plasmons in two-dimensional electron channels

O. Sydoruk, V. Kalinin, and L. Solymar A terahertz (THz) instability can occur when optical phonons interact with drifting solid-state plasmas. We developed a theoretical model for the optical-phonon instability in two-dimensional electron channels. The paper derives the dispersion relation and analyzes the instability using parameters m ...
