Deep Ultraviolet Photodetector: Materials and Devices

The application of deep ultraviolet detection (DUV) in military and civil fields has increasingly attracted the attention researchers’ attention. Compared with disadvantages organic materials, such as complex molecular structure poor stability, inorganic materials are widely used field DUV because their good controllable growth, other characteristics. Rapid advances preparing high-quality ultrawide-bandgap (UWBG) semiconductors have enabled realization various high-performance photodetectors different geometries, which provide an avenue for circumventing numerous traditional detectors. Herein, development history types detectors briefly introduced. Typical UWBG preparation methods, well research status detection, emphatically summarized reviewed, including III-nitride semiconductors, gallium oxide, diamond, etc. Finally, problems pertaining to growth performance devices, future development, also discussed.
