High Responsivity Solar Blind Detector Based On Zn

Several Army applications that utilize ultra violet light emitting diodes (UV LEDs) require high responsivity solar blind detectors (SBDs) what will replace currently used PMTs. On-going development efforts in each of SiC and GaN based APDs have not yet met the performance requirements Tanner Research is proposing to leverage recent developments in ZnO UV photodetectors to build a high responsivity SBD with sufficiently low dark current noise. We will use proven concepts and take full advantage of our prior knowledge and experiences in recent experimental demonstration of a high gain ZnO UV detector. In Phase I, we will provide key design parameters in building the final device.
