阅读:719发布:2021-02-08

专利汇可以提供HIGH PERFORMANCE ULTRAVIOLET IMAGER FOR OPERATION AT ROOM TEMPERATURE专利检索,专利查询,专利分析的服务。并且A photodetector sensitive to ultraviolet wavelengths is capable of single photon sensitivity at room temperatures and video frame rates. It includes (a) a compound semiconductor photodiode (38), biased below its avalanche breakdown threshold, comprising III-V elemental components and having a bandgap with transition energy higher than the energy of visible photons; and (b) a high input impedance MOS interface circuit (26), arranged to receive a signal from the photodiode junction and to amplify said signal. Preferably, the photodiode junction is integrated in a first microstructure (22) on a first substrate (30), and its interface circuit in a second microstructure (26) on a second substrate (66). Both microstructures are then joined in a laminar, sandwich-like structure and communicate via electrically conducting contacts (24).,下面是HIGH PERFORMANCE ULTRAVIOLET IMAGER FOR OPERATION AT ROOM TEMPERATURE专利的具体信息内容。
