SCLC theory for a Gaussian trap distribution

Abstract

A simplified one-carrier space charge limited conduction theory has been developed for a Gaussian trap distribution in. an insulator. It is shown that the distribution behaves much like a discrete trap level at low applied fields, although the current has a temperature dependent activation energy. At higher fields the current-voltage relation becomes superquadratic, but this does not account for the behaviour normally attributed to an exponential trap distribution.
