Solid-State UV Photodetectors Search for a Niche
Jan 1, 2003 — Commercial solid-state UV photodetectors did not exist until around 1996 when Cree Research in Durham, N.C., began production of silicon carbide photodiodes. Since then, additional materials have debuted commercially, including GaN, AlGaN and TiO2. Because of their relative newness, these devices are -- like lasers were in the 1960s -- solutions in search of a problem.Potential applications of solid-state UV sensors are flame sensing, lamp control in UV sterilization and curing-dose regulation,...
