Quasi-pseudomorphic AlGaN based deep ultraviolet LEDs over sapphire substrates

Abstract

III-Nitride sub-290 nm deep ultraviolet (DUV) light emitting diodes (LEDs) have the potential to replace the existing mercury lamps used in air/water purification, Bio-agent detection, Phototherapy and biomedical instruments sterilization applications. Most of the research activity1-2 has been so far focused on improving the DUV LED's external quantum… (More)
