Professor Christian Wetzel (RPI) presented new work on higher efficiency lighting and power device technology at Semicon West in San Francisco: “Energy efficiency and green technology with wide bandgap GaN-based epitaxy”. Energy from currently used LED’s is lost to heat through the back of the LED and/or imparted to the phosphor needed to provide the color or shade of lighting desired. The ERC is working on developing technology that would lessen the dependency on phosphors, optimizing the wavelength of the light and improve the efficiency of the LED.
