Narrow and Stable GaN/AlGaN UV Light Source by Using Strain Relaxing Superlattices

Not Accessible

Your library or personal account may give you access

Abstract

A GaN/Al0.3Ga0.7N UV light source with GaN/AlxGa1-xN strain relaxing superlattices on c-plane sapphire was proposed. Narrow and much more stable emission on excitation power with relaxed strain were demonstrated by micro-PL and Raman spectroscopy.
