A group of researchers at the University of California, Riverside Bourns College of Engineering have developed a technique to keep cool a semiconductor material used in everything from traffic lights to electric cars.
Gallium Nitride (GaN), a semiconductor material found in bright lights since the 1990s, is used in wireless applications due to its high efficiency and high voltage operation. However, the applications and market share of GaN electronics is limited because it is difficult to remove heat from them.
That could change due to a technique developed by the Nano-Device Laboratory research group led by Alexander Balandin, professor of electrical engineering and founding chair of Materials Science and Engineering program.
