Abstract

An investigation of "impurity-shifted" intersubband transitions in n-inversion layers of (100) Si MOSFETs whose oxides were purposely contaminated with mobile positive ions during processing has been carried out to study localization of electrons in two-dimensional systems. Results provide evidence for screening of the "impurity-shifted" transitions at high values of channel electron density.
