Dependence of the 0.5(2e2/h) conductance plateau on the aspect ratio of InAs quantum point contacts with in-plane side gates
P. P. Das, A. Jones, M. Cahay +6
The observation of a 0.5 conductance plateau in asymmetrically biased quantum point contacts with in-plane side gates has been attributed to the onset of spin-polarized current thr…
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…
Influence of Impurity Scattering on the Conductance Anomalies of Quantum Point Contacts with Lateral Spin-Orbit Coupling
J. Wan, M. Cahay, P. P. Das +1
We have recently shown that asymmetric lateral spin orbit coupling (LSOC) resulting from the lateral in-plane electric field of the confining potential of a side-gated quantum poin…
