Non linear hole transport through a submicron-size channel was investigated. The channel was fabricated from a modulation-doped p-type GaAs/(AlGa)As single-quantum-well heterostructure. It was showed that the holes can be accelerated beyond the inflection point of the lowest energy subband dispersion curve by the intense electric field in the channel.
