摘要
Terahertz radiation is demonstrated to generate phonon-induced resistance oscillations in two-dimensional electron gases. This effect dominates over microwave-induced resistance oscillations in the low terahertz range, but could not be detected in the gigahertz regime. Possible mechanisms for phonon generation are discussed.
