USING NONEQUILIBRIUM ACOUSTIC PHONONS TO PROBE DISORDERED QUANTUM WIRES

Kent and co-workers at Nottingham recently performed an experiment in which non-equilibrium acoustic phonons were used to investigate the st ructure of an electron gas confined to a split-gate GaAs/(AlGa)As quan tum wire. We explore the possibility of using non-equilibrium phonons to probe the effects of wire disorder on the electron gas.
