Keyes figure of merit
WebJohnson's figure of merit is a measure of suitability of a semiconductor material for high frequency power transistor applications and requirements… Wikipedia Create Alert … WebAlong with Johnson’s figure of merit, the additional considerations of doping, low field mobility, thermal constraints, and heterojunctions are discussed. The analysis is used to explain why gallium nitride-based high electron mobility transistors have become the material system of choice for high power high frequency applications.
