Paper Abstract

High-quality gallium nitride (GaN) films were prepared on Si substrates by sputtering post-annealing-reaction technique. XRD, XPS, and SAED reveal that the films consists of hexagonal wurtzite GaN wiht c-axis oriented polycrystalline grains. A strong UV photoluminescence located at 354 nm is observed for room temperature measurement. The bandgap of these films has a blueshift wiht respect to bulk GaN.
