Abstract The current–field characteristics for Al x Ga1−x As alloys under hydrostatic pressure have been calibrated into velocity-field characteristics using low field experimental data. The saturated drift velocity for x = 0.29 decreases from 7.8 × 106 cm/s at P = 3.5 Kbar to 3.8 × 106 cm/s at P = 8 Kbar. It is shown that the saturated velocity decreases from the value of 1.0 × 107 cm/s in GaAs to about 3.8 × 106 cm/s for x ≍ 0.39. The results should be useful in the design of high field devices of Al x Ga1−x As.
