Abstract

Cathodoluminescence is applied for evaluation of in‐plane variations of light emission from GaN‐based laser diode structures. We demonstrate that potential fluctuations affect significantly emission of laser diodes for e‐beam currents above thresholds for a stimulated emission. (© 2006 WILEY‐VCH Verlag GmbH & Co.
