Hysteresis in the Conductance of Asymmetrically Biased GaAs Quantum Point Contacts with in-plane Side Gates
N. Bhandari, M. Dutta, J. Charles +2
We have observed hysteresis between the forward and reverse sweeps of a common mode bias applied to the two in-plane side gates of an asymmetrically biased GaAs quantum point conta…
Tunable All Electric Spin Polarizer
J. Charles, N. Bhandari, J. Wan +2
We propose a new device to create a tunable all-electric spin polarizer: a quantum point contact (QPC) with four gates -- two in-plane side gates in series. The first pair of gates…
Spin Polarization in a AlGaAs/GaAs Quantum Point Contact with in-plane side gates
N. Bhandari, P. P. Das, M. Cahay +2
We report the observation of an anomalous conductance plateau near G = 0.5 G0 (G0 = 2e2/h) in asymmetrically biased AlGaAs/GaAs quantum point contacts (QPCs), with in-plane side ga…
Anamolous conductance plateau in an asymmetrically biased InAs/InAlAs quantum point contact
P. P. Das, K. B. Chetry, N. Bhandari +4
The appearance and evolution of an anomalous conductance plateau at 0.4 (in units of 2e2/h) in an In0.52Al0.48As/InAs quantum point contact (QPC), in the presence of lateral spin-o…
