Abstract
The dc mobility of two-dimensional electrons on the surface of helium liquid is calculated with the quantum degeneracy of the electron distribution and the effect of multisubband occupation taken into account. The subband structure is obtained from a self-consistent Schrödinger equation with the inclusion of the Hartree and exchange-correlation potentials. It is shown that the effect of higher subband population of electrons is small for low temperatures and the calculated mobility gives better agreement with the experimental results than that one obtained with the Maxwellian electron distribution for moderate electron concentrations. The effect of screening is briefly discussed.
