2020/8/21· A high electron mobility transistor (HEMT) is a transistor with a channel with high electron mobility. An important performance characteristic of a gallium nitride (GaN) HEMT is its high breakdown voltage. To improve this voltage, the GaN (grown via metal-organic chemical vapor deposition) is doped with carbon atoms, yet this increases the density of V-pits, which lower the device quality. In
