Characterization of AIGaN-based metal - semiconductor solar-blind UV photodiodes with IrO2 Schottky contacts

Van Schalkwyk, Louwrens; Meyer, Walter Ernst; Auret, Francois Danie; Nel, Jacqueline Margot; Ngoepe, Phuti Ngako Mahloka; Diale, M. (Mmantsae Moche) (Elsevier, 2012-05)

Intrinsically solar-blind ultraviolet (UV) AlGaN-based Schottky photodiodes were fabricated using Iridium oxide (IrO2) as the Schottky barrier material. The Ir Schottky contacts were annealed at 700 °C under O2 ambient and ...
Development and characterization of a tuneable AlGaN-based solar-blind UV-sensitive Schottky photodiode

Van Schalkwyk, Louwrens (University of Pretoria, 2015)

Several applications require the detection of terrestrial UV-C signatures. Efficiency, compactness, environmentally friendly and cost-effective requirements for UV-C–detectors resulted in a research interest in wide-bandgap ...
