UV pump-THz probe study of mechanisms limiting luminescence from nanoscale compositionally inhomogeneous AlGaN

Abstract

We present ultraviolet pump-terahertz probe and photoconductive decay measurements on nanoscale compositionally inhomogeneous AlGaN. Results compared to photoluminescence and time-resolved photoluminescence measurements indicate luminescence from the material is limited by hole trapping.
