Abstract / Description:We investigate hole transport through a submicron-size channel
fabricated from a modulation-doped p-type GaAs/(AlGa)As single-
quantum-well heterostructure. The intense electric field in the
channel accelerates the holes beyond the inflection point of
the lowest energy subband dispersion curve. This leads to
current saturation and negative differential conduction effects
in the current-voltage characteristics. (C) 2003 American
Institute of Physics.
