Abstract :
We review the performance and discuss the potential of GaN-based field effect transistors for high-power, high-temperature operation. Recent Monte Carlo simulations predict that GaN-based transistors operating at high voltages may outperform GaAs-based transistors even at room temperature. Our GaN/AlGaN doped channel HFETs (DC-HFETs) demonstrated highest frequency operation among all wide band gap semiconductor devices because of excellent transport properties of two dimensional electron gas at the AlGaN/GaN heterointerface and a large sheet carrier concentration in the device channel, with maximum frequency of oscillations above 100 GHz and cutoff frequency over 40 GHz.
