Graphene-Graphite “Quilt” Removes and Spreads Heat from Hot Spots
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 … [Read more...]
Small Bumps in “Semiconductor Billiards” Have Unexpectedly Large Effect
There’s nothing worse than a pool table with an unseen groove or bump that sends your shot off course: a new study has found that the same goes at the nano-scale, where the “billiard balls” are tiny electrons moving across a “table” made of the semiconductor gallium arsenide. In a research paper titled “The Impact of Small-Angle Scattering on Ballistic Transport in Quantum … [Read more...]
