Schottky barrier heights of nickel-platinum silicide contacts on n-type Si

Abstract
The barrier heights of NiPt silicide–n‐type Si have been determined from the saturation current density of diodes for various concentrations of Ni and Pt. Ni‐Pt films on Si were heated to 475 °C to obtain a NiPt silicide. The barrier height varies smoothly from that of NiSi‐Si to PtSi‐Si with increasing amounts of Pt in the NiPt films. For 19 wt% Pt the barrier is 0.69 eV and for 67 wt% Pt the height is 0.78 eV.
