Impact of surface treatment on metal-work-function dependence of barrier height of GaN-on-GaN Schottky barrier diode

The impact of surface treatment on Schottky contacts on a GaN-on-GaN epitaxial layer was comprehensively investigated by combining X-ray photoelectron spectroscopy (XPS) at each step of the treatment process and electrical measurements on Schottky barrier diodes. XPS showed that a photolithography p...
