Study of Ti/InP interfaces by PES

Abstract The interface of Ti/InP(110) was studied by X-ray photoelectron spectroscopy (XPS) and ultraviolet photoelectron spectroscopy (UPS). It is evident that deposition of Ti on the surface of InP(110) at room temperature introduced a break of the In-P bond and a diffusion of In atoms into the Ti film. The interaction of Ti and P occurred at a temperature of 350°C.
