Influence of the image force on the band gap in semiconductors and insulators

Abstract
The change in potential energy of electrons and holes and the resulting band‐gap change caused by the image force have been calculated close to the insulator‐semiconductor interface. Some examples are given from which it appears that in metal‐insulator‐semiconductor (MIS) structures, as in Schottky diodes, the effects of the image force should not be overlooked.
