Abstract
Within the static screening and binary collision approximations, the authors discuss the influence of the excitonic Mott transition on the optical inter-band density. They calculate semiclassically the changes in the density of states caused by the particle-particle interactions. Further, they follow separately the evolution of the spectrum of electron-hole pair states and the excitonic enhancement factor as a function of the carrier density. The continuous character of the transition becomes evident.File in questo prodotto:
