Tanay Tak has received the 2023 National Defense Science and Engineering Graduate Fellowship! His research focuses on understanding hot electrons to inform the design of next-generation III-Nitride semiconductor devices. 

Materials scientists work on the semiconductors that could transform how we disinfect surfaces, spaces, personal protective equipment — even the air we breathe

CSW2019 is the premier forum for science, technology, and applications in all areas of compound semiconductors.

With the help of DOE funding, researchers at the University of California at Santa Barbara are conducting analyses to determine the mechanisms underlying efficiency loss in light-emitting diodes (LEDs) used in solid-state lighting. The researchers’ efforts focus on understanding the cause of the relatively low efficiency of green LEDs, which is commonly referred to as the “green gap,” as well as of the high-temperature efficiency losses known as “thermal droop.”

The color of LED lights is controlled by a clumsy process. A new mathematical discovery may make it easier for us to get the hues we want.

UC Santa Barbara professors James Speck and Larry Coldren are among the newest fellows of the National Academy of Inventors (NAI).

The startup sees a 75 percent boost in efficiency with its LED bulb, a new material platform for bringing down the cost of LEDs for general lighting
