By taking the effects of Ge fraction and strain on the energy band structure and effective masses into account, the analytical model of the effective densities of states of the conduction and valence bands are proposed, and the temperature and Ge fraction dependence of the effective densities of states are also studied. Following this, the temperature and Ge fraction dependence of intrinsic carrier concentration in strained SiGe layers are analytically calculated. Furthermore, carder freezeout effect and the minority carrier trapping effect of the shallow-level compensated imputities in strained SiGe layers at low temperatures are investigated.
