We report on experimental studies of high-field electron transport in AlGaN∕GaN two-dimensional electron gas. The velocity–electric field characteristics are extracted from 10to30ns pulsed current–voltage measurements for 4.2 and 300K. An electron drift velocity as high as 1.7×107cm∕s was obtained in the fields 150kV∕cm. Estimates of thermal budget of the system show that overheating of the electrons exceeds 1700K at highest electric fields achieved in the experiment.
