International technology roadmap for wide band-gap power semiconductor ITRW

Wide band-gap devices are highly suitable to harsh working conditions such as high voltage, high temperature, high frequency, and high radiation exposure. The working voltage can reach as high as 10,000 volt, while the heat flux can exceed 1 *107 W/m2, which is far beyond the realm of Si devices. Applications include spaceship, airplane, high speed train, ocean oil drilling platform, EV /HEV and intelligent manufacturing. Application areas of internet of things (loT) require new technologies such as power electronics, RF devices and solid state lighting.
