Abstract
Effects of exchange and correlation at finite temperature on subband energies in Si(100) -channel inversion layers have been studied using a perturbational technique, and quantitative agreement with experiments has been obtained. A parallel calculation employing a local temperature-independent exchange-correlation potential gives similar results for , indicating that the change in occupancy of subbands is the major effect of temperature.
