摘要：
In this we report on the electrical characteristics and surface morphology of four different metal contacts (Ag, Ti, Pt and Ni) on GaN films grown on silicon substrate. The samples were annealed at different temperatures ranging from 300 C degrees to 900 degrees C under flowing nitrogen gas for 15 minutes. The electrical behaviors of the contacts were analyzed by current-voltage (I-V) measurements. Scanning electron microscopy (SEM) measurements and energy dispersive spectroscopy (EDS) were carried out to examine the surface morphology and chemical composition of the metal contacts.
