Developing an Eco-Friendly Deep-UV Lamp

Facebook X LinkedIn Email
Using atomically controlled thin monolayers of gallium nitride (GaN) and aluminum nitride (AIN) as active regions, a research group has shown the ability to produce deep-UV emission with an LED between 232- and 270-nm wavelengths. Currently, most deep-UV lamps are mercury-based and are bulky and inefficient. A deep-UV LED would provide a smaller, more eco-friendly alternative to a mercury lamp. Researchers at Cornell University, along with collaborators from the University of Notre Dame, achieved electrically injected deep UV emission using monolayer thin GaN/AlN quantum structures as...Read full article
