WebOf Ni, Pd, and Pt, it is expected that Pt will most easily form an ohmic contact due to its large metal work function. All samples are taken from the same 2" Mg-doped GaN wafer (308) whose hole concentration and mobility at room temperature are 5-6x10•6 cm 3 and 7 cm 2/V-s, respectively. Previous studies of ohmic contacts to n-GaN have shown ...
WebNo reactions occur in the Pt, Pd, and Ni systems with annealing up to 800°C. The Pt film begins to form submicron spheres and islands after annealing above 600°C. The Pd and Ni films begin to island with annealing above 700°C. Below these temperatures no structural changes were observed.
