Due to efficiency droop and green gap problems, the first generation nitride-based emitter materials for solid-state lighting have reached a bottleneck. Industry and academia are calling for the next generation materials.
After 6 years of laboratory research at Yale University, Professor Jung Han and his Nitride Group developed the world's first mass-producible semi-polar GaN materials on a large-size wafer, pointing out an innovative way to better illuminate the world. Saphlux was founded by Prof. Jung Han and Dr. Chen Chen to commercialize these new materials and to revolutionize solid-state lighting. Backed by venture capitalists, Saphlux now operates in New Haven, Connecticut.
