Decay of spin polarized hot carrier current in a quasi one-dimensional spin valve structure
S. Pramanik, S. Bandyopadhyay, M. Cahay
We study the spatial decay of spin polarized hot carrier current in a spin-valve structure consisting of a semiconductor quantum wire flanked by half-metallic ferromagnetic contact…
Magnetoelectric subbands and eigenstates in the presence of Rashba and Drresselhaus spin orbit interactions in a quantum wire
S. Bandyopadhyay, S. Pramanik, M. Cahay
We derive the eigenenergies and eigenstates of electrons in a quantum wire subjected to an external magnetic field. These are calculated in the presence of spin orbit interactions…
Effect of Disorder on the Conductance of Spin Field Effect Transistors (SPINFET)
M. Cahay, S. Bandyopadhyay
We show that the conductance of Spin Field Effect Transistors (SPINFET) [Datta and Das, Appl. Phys. Lett., Vol. 56, 665 (1990)] is affected by a single (non-magnetic) impurity in t…
Spin transport in nanowires
S. Pramanik, S. bandyopadhyay, M. Cahay
We study high-field spin transport of electrons in a quasi one-dimensional channel of a gate controlled spin interferometer (SPINFET) using a semiclassical formalism (spin d…
Phase coherent quantum mechanical spin tranport in a weakly disordered quasi one-dimensional channel
M. Cahay, S. Bandyopadhyay
A transfer matrix technique is used to model phase coherent spin transport in the weakly disordered quasi one-dimensional channel of a gate-controlled electron spin interferometer…
The Effect of Ramsauer Type Transmission Resonances on the Conductance Modulation of Spin Interferometers
M. Cahay, S. Bandyopadhyay
We use a mean field approach to study the conductance modulation of gate controlled semiconductor spin interferometers based on the Rashba spin-orbit coupling effect. The conductan…
