The effect of (NH4)2Sx passivation on the (311)A GaAs surface and its use in AlGaAs/GaAs heterostructure devices
D. J. Carrad, A. M. Burke, P. J. Reece +6
We have studied the efficacy of (NH4)2Sx surface passivation on the (311)A GaAs surface. We report XPS studies of simultaneously-grown (311)A and (100) heterostructures showing tha…

The origin of gate hysteresis in p-type Si-doped AlGaAs/GaAs heterostructures
A. M. Burke, D. Waddington, D. Carrad +9
Gate instability/hysteresis in modulation-doped p-type AlGaAs/GaAs heterostructures impedes the development of nanoscale hole devices, which are of interest for topics from quantum…
