讨论了器件进一步发展的方向。
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.
