Far-UVC

Research

Groundbreaking technologies begin as exceptional research.

Lit Thinking is enabling world-leading semiconductor research in collaboration with academic and industrial partners. Currently, UVC LED’s are not efficient at wavelengths below 230nm. Our goal is to develop commercially viable semiconductors that will enable Far-UVC emission.

Our work will change the world.
