Phonon Controlled Temperature Dependence of Electron Mobility in 2DEG of GaAs Surface Layer

Authors(1) :-A. K. Ghorai

The acoustic phonon limited zero-field mobility of free electrons is estimated in a degenerate two dimensional elec┬Čtron gas (2DEG) formed in semiconductor interface considering the effect of screening of the free carriers and the true phonon distribution which are indeed dominant characteristics of electron-phonon scattering at low lat┬Čtice temperatures. Numerical calculations are made to observe the effect of screening on mobility values in GaAs surface layer and the result obtained here is compared with available experimental data and other theoretical result.
