Abstract :
We demonstrate room temperature lasing in the UV-C spectral range (-275 nm) with nitride microdisks. The nitride materials are directly grown on a silicon substrate. The active region consists of ultra-thin GaN/AIN quantum wells and is a promising alternative to the most investigated designs based on AlGaN quantum wells grown on complex buffer layers.
