Abstract

GaN films were prepared on Al$_2$O$_3$(1120) substrates by hydride vapor phase epitaxy (HVPE) with HCl-NH$_3$-N$_2$ gas system. The growth rate was increased with increasing the substrate temperature below 1050$^{\circ}C$ and decreased over the temperature, increased with growth time. The X-ray diffraction patterns showed only (0002) GaN peak. The UV-Visible Spectrophotometer showed a good optical absorption and fundamental absorption occurred at 3700${\AA}$.
