Mott transition in electron-hole plasmas

In connection with the ionization equilibrium of an electron-hole plasma in a highly excited semiconductor, the influence of many-particle effects on both the chemical potentials of carriers and the Mott transition of para-excitons in zinc selenide (ZnSe) is investigated over a wide range of temperatures and carrier densities. Special attention is directed to the determination of the region where an excitonic fraction can exist and, therefore, a possible Bose-Einstein condensate can occur at low temperatures.
