Electron states in<i>n</i>-type inversion layers with periodic microstructure

Abstract

The electron states of an inversion electron layer with a periodic density modulation are calculated self-consistently in a mean-field approximation. It is shown that drastic changes in the electronic properties occur as the modulation and the electron density are varied. In particular the electron-electron interaction has strong effects on the localization of the inversion electrons. The transition from localized to extended behavior is quite abrupt as a function of the electron density.
