Palladium-Based Contacts on p-GaN and Their Application in Laser Diodes

Palladium-Based Contacts on p-GaN and Their Application in Laser Diodes

In this paper, we investigate the effect of Pd thickness and heat treatment on Pd/Ni/Au/p-GaN metal contacts. The as-deposited samples exhibit a smooth morphology and non-linear I–V characteristics. Heat treatment in a N<sub>2</sub> atmosphere leads to degradation of the contact microstr...
