Popis: We report measurements of the drift velocity of holes in silicon inversion layers. The saturation velocity of holes at 300 K is found to be strongly dependent on the effective vertical field. No hole velocity overshoot was observed down to 0.16 /spl mu/m channel length at room temperature. At 77 K, hole velocity saturation is much less pronounced, and a 10% higher average velocity is observed for 0.16 /spl mu/m channel length as compared to 0.36 /spl mu/m channel length.
