This NSF Engineering (CFDA 47.041) Project Grant award of $549,999 to the University of Wisconsin System aims to significantly improve the efficiency of ultraviolet (UV) light emitting diodes (LEDs). The 5-year project will develop flexible, mechanically compliant materials and semiconductor reflector structures to enhance light extraction and address efficiency challenges in the 280-365 nm UV wavelength range. This work seeks to enable a new class of high-power UV LEDs with up to a 10x efficiency improvement over current solutions. The research will explore experimental and computational modeling approaches to advance UV emitter technologies, with potential applications in medical treatments, agriculture, sanitization, and security systems. The award also includes broader impacts activities such as curriculum development and workforce training to promote semiconductor education and expand the national talent pool in this domain.
