Silanna UV will give a Plenary talk & exhibit First International Congress on Far-UVC Science & Technology (ICFUST) host by Columbia University

June 14^th to 16^th, Silanna UV will proudly give a Plenary talk & Exhibit at First International Congress on Far-UVC Science & Technology (ICFUST)  in New York, USA. The background to this meeting is the enormous worldwide impact associated with indoor airborne disease transmission. Covid-19 has made us all realize that new and better approaches are needed to prevent worldwide disruptions from this and the next pandemic, as well as from yearly seasonal flu epidemics. Far-UVC light has shown a lot of promise to be the disruptive technology that is so badly needed. The background here is that conventional UVC light (wavelength 254 nm) has been known for decades to be efficient at killing viruses and bacteria in the air and on surfaces, but it can’t be used directly in occupied public spaces as it is a potential health hazard to skin and eyes. All the far-UVC researchers in this highly multi-disciplinary field to come together for the first time to discuss latest results and to plan for the future.

Silanna UV will talk about AlGaN based far UVC LEDs in general suffer from poor carrier injection, low light extraction and high drive voltage due to the inherit limitations of high Al-content AlGaN. To overcome these issues, a short period superlattice (SPSL) based far UVC LED structure is proposed.
