Research Abstract

We have investigated stimulated emission processes in ZnO, which has been intensively studied from the interest in the application of optoelectronic device in a near ultraviolet region. In this work, we report on the existence of the stimulated emission process from a phonon sideband of an electron-hole plasma in a ZnO thin film.
