Abstract
Acoustic emission was detected during the degradation of GaP : N light‐emitting diodes and was shown to have a correlation with the generation of dislocations near the p‐n‐junction plane. This technique provides us with a powerful tool to investigate dislocation motion on real time and in a nondestructive way.Keywords
