The Ni silicide nanowires were grown by physical vapor deposition. The morphological changes of silicide formation were observed on a gradient Ni film thickness, which visualized the critical thickness is 60-80 nm to grow nanowires. The field emission measurement provided uniform characteristics and high field enhancement factors were obtained to be 3180 and 3002 from the Ni silicide nanowires grown on a Si substrate and a tungsten plate, respectively. By using a conductive tungsten plate, the emission current was enhanced to be 172.5 μA/cm2 comparing to 76.5 μA/cm2 from a Si substrate at 5 V/μm.
