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…
A Dual Gate Spin Field Effect Transistor With Very Low Switching Voltage and Large ON-to-OFF Conductance Ratio
J. Wan, M. Cahay, S. Bandyopadhyay
We propose and analyze a novel dual-gate Spin Field Effect Transistor (SpinFET) with half-metallic ferromagnetic source and drain contacts. The transistor has two gate pads that ca…
A Digital Switch and Femto-Tesla Magnetic Field Sensor Based on Fano Resonance in a Spin Field Effect Transistor
J. Wan, M. Cahay, S. Bandyopadhyay
We show that a Spin Field Effect Transistor, realized with a semiconductor quantum wire channel sandwiched between half-metallic ferromagnetic contacts, can have Fano resonances in…
