A: Applications and Materials Science 202(14), pp.R161-R163Formation of low resistance and thermally stable ohmic contacts to GaN is of considerable importance for device applications. Several metallization schemes for ohmic contacts to n-GaN with low contact resistance have been proposed and investigated by different techniques. We investigate 500 Å Ti/n-GaN contacts of as-deposited and rapid furnace annealed at 900 °C for 30 s, using X-ray diffraction pattern, I–V measurements, and X-ray absorption near edge spectra at Ti K- and L3,2-edges and elucidate the mechanism responsible for the high ohmic behaviour. These measurements indicate the formation of an interfacial TixN layer and intermetallic alloys of Ti and Ga
