Investigation of Exciton-Plasma Mott Transition in Si

Abstract
Measurements of luminescence spectra in pure Si demonstrate the dissociation of excitons with increasing excitation intensity. The density at which the dissociation begins and its temperature variation agree well with Mott's predictions. We have also determined a phase diagram of Si, including the effects of electron-hole-liquid and Mott transition.
