Blue/UV Emitters From SiC And Its Alloys

A strong need exists in many commercial and military applications for solid state blue emitters, but until recently a suitable material or material system from which to fabricate these devices had not been commercially developed. Some of the applications for blue emitters include rugged solid-state full color indicators and flat panel displays. The material system used for such emitters will also provide the basis for the development of blue/UV laser diodes. This paper reports on the most recent advancements in increasing the performance of blue light emitting diodes fabricated in 6H-Sic and the potential for Sic-nitride based alloys.
