AtLv-AlGaN

FY2023-FY2025: The purpose of this project is to develop deep-ultraviolet LEDs that contribute to the destruction and inactivation of RNA and DNA of coronaviruses and bacteria. Specifically, (1) a team from Poland and Japan will analyze physical properties such as adsorption probabilities of precursor atoms and molecules on the crystal growth surface, and (2) a team from Bulgaria will develop a digital twin (a digital replica of real space): step dynamics simulation code implementing the obtained physical properties. (3) A team from Japan will predict the crystal growth conditions to obtain atomically flat surfaces/interfaces by machine learning using the developed digital twin. Based on the above findings, (4) a team from Japan will fabricate deep-ultraviolet LEDs by AlGaN metal-organic vapor phase epitaxy (MOVPE), contributing to the realization of a clean, safe, and secure society through joint research by four teams from three countries.
