We describe a simulation of the self-consistent fields and mobility in (100) Si-inversion layers
for arbitrary inversion charge densities and temperatures. A nonequilibrium Green's functions
formalism is employed for the state broadening and conductivity. The subband structure of
the inversion layer electrons is calculated self-consistently by simultaneously solving the
Schrödinger, Poisson and Dyson equations. The self-energy contributions from the various
scattering mechanisms are calculated within the self-consistent Born approximation. Screening
is treated within RPA. Simulation results suggest that the proposed theoretical model
gives mobilities which are in excellent agreement with the experimental data.
