Overview

Ultraviolet lasers require operation at high currents and high powers, making vertical device structures advantageous. To achieve this structure, a delamination technique using pressurized hot water on nano-pillar-patterned AlN layers has been reported. The formation state of the AlN nano-pillars significantly affects the delamination characteristics and the crystallinity of the overlying AlGaN layer. This presentation reports on the results of the AlN nano-pillar layer evaluated using multiple analytical techniques based on X-ray diffraction method.
