Abstract

GaN high electron mobility transistor (HEMT) has been widely acknowledged for use in high-frequency

high-power

and high-temperature applications because of their features such as its wide band gap

high electron saturation velocity

high 2-DEG density at the hetero-interface

high breakdown voltage (BV)

and high thermal conductivity. The issues that limit the gallium nitride high electron mobility transistor device performance improvement and some solutions are introduced firstly. And then

the latest research progress on the high-frequency

high-power area of gallium nitride high electron mobility transistor is reviewed in detail with focus on the material structural design and the device structural design. Finally

the direction for the development of the device is discussed briefly.
