High-Efficiency Ultraviolet Light Emitting Diodes to Sterilize Pathogens, Including COVID-19
ECE Ph.D. student Ayush Pandey details the research led by Prof. Zetian Mi of the University of Michigan on using high efficiency ultraviolet light emitting diodes to sterilize pathogens. This research, “High-efficiency AlGaN/GaN/AlGaN tunnel junction ultraviolet light-emitting diodes,” won the 2020 Editor-in-Chief Choice Award from Photonics Research. Every year, thousands of lives and billions of dollars are spent worldwide as a result of health-care associated and waterborne illnesses. Sterilization is a critical preventative measure and it can be achieved by a number of techniques including irradiation using ultraviolet (UV) light. This need has gained greater urgency because of the…
