The ZnNi ss/Ag scheme was investigated to achieve low resistance and highly reflective ohmic contacts for use in flip-chip LEDs. The contacts produced specific contact resistances. MQW blue LEDs fabricated with the annealed ZnNi ss/Ag p-type contact layers showed a forward-bias voltage of 3.24 V at an injection current of 20 mA.
