Abstract

The purpose of this study is to experimentally determine the effect of electron injection on the minority carrier lifetime in Gallium Nitride. Earlier studies of electron injection in GaN have provided an indirect proof of lifetime enhancement through the increase of minority carrier diffusion length and the decrease in the cathodoluminescence intensity. These changes in the minority transport properties, caused by electron injection, are brought forth through defect and trap levels in the bandgap. Furthermore, a thorough discussion of the electron injection model and role of these trap levels is presented.
