【Abstract】 The research progress of Ⅲ-Nitride promotes the development and the application of all kind GaN-based devices.Especially,the GaNbased ultraviolet photo-detector can adjust the cut-off wavelength through changing the Al content in the Al_xGa_1-xN materials.And the Al_xGa_1-xN with high Al content can be used to fabricate the solar-blind photo-detectors,which induces our attention greatly.The basic characters of the ultraviolet photo-detector,including the ultraviolet wavelength and atmosphere absorption,etc,are presented briefly.Then,the GaN-based Photo-detector device research progress is reviewed,such as the P-GaN doping,metal-semi contact and etching problems,etc.Finally,the resent developments of the ultraviolet detector,especially the ultraviolet FPA,are introduced.更多还原
