Electrical field effects in n-type MOSFET and metal–nonmetal transition

Abstract

The effects of disorder, correlation, external electric field, impurity concentration, and impurity location near and at the Si/SiO2 interface of a metal-oxide semiconductor field effect transistor (MOSFET), have been investigated. The binding and correlation energies are strongly dependent on the electric field and impurity location. The Hubbard–Mott like model provides further evidence of a MNM transition in agreement with recent experimental findings.
