The properties of GaN thin films grown by molecular beam epitaxy at temperatures from 80 to 500 C under a wide range of Ga: N flux ratios are studied. We found that at growth temperatures as low as~ 80 C, GaN films still have a polycrystalline, columnar morphology with c-axis preferred orientation. Soft x-ray absorption and emission and optical absorption measurements on Ga-rich samples suggest the presence of a partially occupied Ga N antisite defect band located at~ 1.2 eV below the conduction band minimum. P-type conductivity observed in this LTMBE Ga-rich GaN is consistent with transport within this partially occupied defect band.
