Abstract
"This STTR Phase I effort will develop a Gallium Nitride avalanche photodiode detector array. The detector array will be sensitive in the UV, but will use a photoelectron avalanche mechanism that is applicable to detectors working at other wavelengths. Assuch the core technology can be readily extended to shorter UV wavelengths with the substitution of a different semi-conductor photo-sensitive electrode, such as SiC. The core technology can also be readily extended to IR wavelengths, again by thesubstitution of photo-sensitive electrode. The universal wavelength avalanche mechanism is a micro-discharge. These novel discharges feature small dimensions, of order 50microns, and high operating pressure. Our team has shown arrays of up to 900micro-discharge elements in a few square mm with a silicon electrode. This work will extend the effort to UV sensitive photo-electrodes. Phase I will demonstrate the effect with a UV sensitive electrode. The research will lead to a broad range of verysimple, amplifiying photo-detector arrays. The long term result will be sensitive detectors and inexpensive development and fabrication. The detectors can be used in hyper spectral imaging, remote sensing and machine vision."
