Abstract

An ultraviolet (UV) radiation emitting device includes an epitaxial heterostructure comprising an AlGaInN active region. The AlGaInN active region includes one or more quantum well structures with Al content greater than about 50% and having a non-c-plane crystallographic growth orientation. The AlGaInN active region is configured to generate UV radiation in response to excitation by an electron beam generated by an electron beam pump source.
