Abstract

A study was performed on optical phonon instability induced by drifting electrons in semiconductor nanostructures. The instability was observed when the electron drift velocity was larger that the phase velocity of optical phonons. The effect was demonstrated in p-i-n semiconductor nanostructures by using Raman spectroscopy.
