Formation of a low-resistance and high reflectivity reflector on p-type GaN with a AgAl Ohmic contact
In this study, we investigate the effect of the Al composition of a AgAl alloy reflector deposited on a p-GaN layer for use in a high-efficiency GaN flip-chip light-emitting diode (FCLED) or n-type sideup vert...
