2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/219933We report on the temperature dependence of microwave-induced resistance oscillations in high-mobility two-dimensional electron systems. We find that the oscillation amplitude decays exponentially with increasing temperature, as $\exp(-αT^2)$, where $α$ scales with the inverse magnetic field. This observation indicates that the temperature dependence originates primarily from the modification of the single particle lifetime, which we attribute to electron-electron interaction effects.4 pages, 4 figures, submitted to Phys.
