Abstract

Microscopic deep defect characteristics of the blue laser materials in the II-VI and III-V wide-bandgap semiconductors have been studied from the view point of the device performance and degradation. The deep defect centers, monitored by transient capacitance spectroscopy technique, have revealed quite different properties in electrical activity, defect density and carrier injection enhanced generation of the defects for the two different wide-bandgap blue laser materials.
