Investigation of the Effects of Forming Gas Annealing on Al2O3/GaN Interface
In this work, the effects of post-deposition annealing in forming gas ambient on the structure of the Al2O3/GaN interface are investigated. Using capacitance–voltage (C–V) and conductance–frequency (G–f) measurem...

Removal of Dry-Etch-Induced Surface Layer Damage from p-GaN by Photoelectrochemical Etching
A non-thermal method for removal of surface damage created by dry etching has previously been documented or n-GaN, but no such effort has been reported for p-GaN. In this study, Ga-polar p-GaN films were subjecte...
