Non-Equilibrium Two Dimensional Electron-Lattice Interaction at Low Temperature

At low lattice temperature (less than20 K) a theory of the average rate of energy loss of non-equilibrium electrons in a two dimensional electron gas (2DEG) formed in semiconductor inversion layer has been developed here when the electrons interact only with the intravalley acoustic mode lattice vibrations. The results obtained from the theory both under low and high temperature conditions are compared and the utility of the theory in studying the high field electron transport in 2DEG is discussed.
