關鍵字: | Ni/Au contacts;p-GaN;p-NiO;X-ray absorption | 公開日期: | 2001 | 卷: | 8 | 期: | 2 | 起(迄)頁: | 827-829 | 來源出版物: | Journal of Synchrotron Radiation | 摘要: | X-ray absorption spectroscopy was used to investigate the electronic structure of as-deposited and oxidized Ni/Au contacts to p-GaN and to elucidate the mechanism responsible for low impedance. X-ray absorption near edge spectra of Ni K- and L3,2-edges clearly indicate formation of NiO on the sample surface after annealing. The reason for low impedance may be attributed to increase in hole concentration and existence of p-NiO layer on the surface. |
