Abstract

The existence of reference levels of signals which determine directly the temperature dependence of emission factor in deep level transient phenomena is discussed. The basic algebraic structure of reference levels in the classical DLTS is studied and various signal forms with derived reference levels are given. We then demonstrate the use of these signal forms and compare them with the classical DLTS double boxcar signal.
