Quasi-Two-Dimensional Electron–Hole Liquid in Shallow SiGe/Si Quantum Wells
Journal Article

· Russian Physics Journal
An analytical expression is obtained for the energy of a quasi-two-dimensional electron-hole liquid (EHL) in shallow quantum wells. It is shown that in the Si/Si{sub 1–x}Ge{sub x}/Si structures with small x, the EHL contains light and heavy holes. With increasing x, the transition of EHL to a state with heavy holes occurs, and the equilibrium density of electron-hole pairs strongly decreases. The effect of an external electric field on the EHL properties is studied.
