Gallium nitride (GaN)-based high electron mobility transistors (HEMTs) are a type of field-effect transistors (FETs) designed to operate at very high frequencies with low noise. As such, they have ...

The word “sputtering” may evoke images of a car engine choking before it fails, but in the high-tech world of advanced coatings, it's a high-speed, high-volume process where superfast ions hit a metal ...
