Quantum size effects on spin-tunneling time in a magnetic resonant tunneling diode
Alireza Saffarzadeh, Reza Daqiq
We study theoretically the quantum size effects of a magnetic resonant tunneling diode (RTD) with a (Zn,Mn)Se dilute magnetic semiconductor layer on the spin-tunneling time and the…
Spin currents and magnetoresistance of graphene-based magnetic junctions
Alireza Saffarzadeh, Mahdi Ghorbani Asl
Using the tight-binding approximation and the nonequilibrium Green's function approach, we investigate the coherent spin-dependent transport in planar magnetic junctions consisting…
Tunnel Magnetoresistance of a Single-Molecule Junction
Alireza Saffarzadeh
Based on the non-equilibrium Green's function (NEGF) technique and the Landauer-Büttiker theory, the possibility of a molecular spin-electronic device, which consists of a single C…
Exchange coupling between two ferromagnetic electrodes separated by a graphene nanoribbon
Alireza Saffarzadeh
In this study, based on the self-energy method and the total energy calculation, the indirect exchange coupling between two semi-infinite ferromagnetic strips (FM electrodes) separ…
Electronic transport through a C molecular bridge: The role of single and multiple contacts
Alireza Saffarzadeh
The effects of different contact geometries, bond dimerization, and gate voltage on quantum transport through a C molecule are studied by the Landauer-Büttiker formula based…
Quantum theory of tunneling magnetoresistance in GaMnAs/GaAs/GaMnAs heterostructures
Alireza Saffarzadeh, Ali A. Shokri
Using a quantum theory including spin-splitting effect in diluted magnetic semiconductors, we study the dependence of tunneling magnetoresistance (TMR) on barrier thickness, temper…
