Design, fabrication and characterization of high-performance solarblind AlGaN photodetectors
(SPIE, 2005)Design, fabrication, and characterization of high-performance AlxGal-xN-based photodetectors for solar-blind applications are reported. AlxGal-xN heterostructures were designed for Schottky, p-i-n, and metal-semiconductor-metal ... -
Dual-color ultraviolet metal-semiconductor-metal AlGaN photodetectors
(AIP Publishing LLC, 2006)Backilluminated ultraviolet metal-semiconductor-metal photodetectors with different spectral responsivity bands were demonstrated on a single Alx Ga1-x N heterostructure. This was accomplished by the incorporation of an ... -
High bandwidth-efficiency solar-blind AlGaN Schottky photodiodes with low dark current
(Pergamon Press, 2005-01)Al0.38Ga0.62N/GaN heterojunction solar-blind Schottky photodetectors with low dark current, high responsivity, and fast pulse response were demonstrated. A five-step microwave compatible fabrication process was utilized ... -
High-performance ALGaN-based visible-blind resonant cavity enhanced Schottky photodiodes
(Materials Research Society, 2003-04)We have designed, fabricated and tested resonant cavity enhanced visible-blind AlGaN-based Schottky photodiodes. The bottom mirror of the resonant cavity was formed with a 20 pair AlN/AlGaN Bragg mirror. The devices were ... -
ITO-schottky photodiodes for high-performance detection in the UV-IR spectrum
(IEEE, 2004)High-performance vertically illuminated Schottky photodiodes with indium-tin-oxide (ITO) Schottky layers were designed, fabricated, and tested. Ternary and quarternary III-V material systems (AlGaN-GaN, AlGaAs-GaAs, ...
