Excitation Wavelength Dependence of Time-Resolved Photoluminescence in Deep-UV MQW LEDs on Bulk AlN

Not Accessible

Your library or personal account may give you access

Abstract

Photoluminescence lifetimes of nearly dislocation free high Al content AlGaN MQW LEDs on bulk AlN are presented as a function of temperature and excitation power for both direct photo-excitation of the wells and barriers.
