We are familiar with the ever increasing use of LEDs in display and lighting applications. Recent work by a group at North Carolina State University on carbon reductions within the AlN substrates within AlN/AlGaN LEDs showed a reduction in UV absorption. The work aims to develop energy-efficient LED devices that use ultraviolet light to kill pathogens such as bacteria and viruses, with uses ranging from drinking-water treatment to sterilizing surgical tools. Commercial applications incorporating this technology are being developed via an NC State spin-off company Hexa Tech, Inc.
