We have proposed a new semi-insulating GaN buffer layer, which consists of multiple carbon-doped and undoped GaN layer. The buffer layer showed sufficiently good semi-insulating characteristics, attributed to the depletion effect between the carbon-doped GaN and the undoped GaN layers, even though the thickness [...]

The SiC and GaN power semiconductor market will exceed $10 billion by 2027!
Key conclusions:
Emerging-market silicon carbide(SiC) and gallium nitride(GaN) power semiconductors are expected to reach nearly $1 billion by 2020, driven by demand for hybrid and electric vehicles, power and photovoltaic (PV) inverters.
The use [...]
