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…
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…
Spin Texture in Quantum Point Contacts in the Presence of Lateral Spin Orbit Coupling
J. Wan, M. Cahay, P. Debray +1
A non-equilibrium Green's function formalism is used to study in detail the ballistic conductance of asymmetrically biased side-gated quantum point contacts (QPCs) in the presence…
The effective spin concept to analyze coherent charge transport in mesoscopic systems
J. Wan, W. Liu, M. Cahay +2
An effective spin concept is introduced to examine the mathematical and physical analogy between phase coherent charge transport in mesoscopic systems and quantum operations on spi…
Possible origin of the 0.5 plateau in the ballistic conductance of quantum point contacts
J. Wan, M. Cahay, P. Debray +1
A non-equilibrium Green function formalism (NEGF) is used to study the conductance of a side-gated quantum point contact (QPC) in the presence of lateral spin-orbit coupling (LSOC)…
