Abstract(in English) | High-frequency measurements of the 1.3-μm-long gate AlGaN/GaN HEMTs have been performed at temperatures between 23℃ and 187℃. The cutoff frequency f_γ decreased monotonically with increasing temperature. It was 13.7 and 8.7 GHz at 23 and 187℃, respectively. The effective electron velocities v_eff in the channel evaluated from the total delay time versus I_D-inverse relation were 1.2 and 0.8 × 10^7cm/s at 23 and 187℃, respectively. It has been shown that the the present device is in an intermediate state between mobility-dominant and peak-velocity-dominant operations. |
