Spin blocker made of semiconductor double quantum well using the Rashba effect
S. Souma, H. Mukai, M. Ogawa +5
We propose a lateral spin-blockade device that uses an InGaAs/InAlAs double quantum well (DQW), where the values of the Rashba spin-orbit parameter are opposite in sign…
Spin Currents in Semiconductor Nanostructures: A Nonequilibrium Green-Function Approach
Branislav K. Nikolic, Liviu P. Zarbo, Satofumi Souma
This chapter of "The Oxford Handbook of Nanoscience and Technology: Frontiers and Advances" reviews nonequilibrium Green function (NEGF) approach to modeling spin current generatio…
Imaging mesoscopic spin Hall flow: Spatial distribution of local spin currents and spin densities in and out of multiterminal spin-orbit coupled semiconductor nanostructures
Branislav K. Nikolic, Liviu P. Zarbo, Satofumi Souma
We introduce the concept of bond spin current, which describes the spin transport between two sites of the lattice model of a multiterminal spin-orbit (SO) coupled semiconductor na…
Can Non-Equilibrium Spin Hall Accumulation be Induced in Ballistic Nanostructures?
Branislav K. Nikolic, Satofumi Souma, Liviu P. Zarbo +1
We demonstrate that flow of longitudinal unpolarized current through a ballistic two-dimensional electron gas with Rashba spin-orbit coupling will induce nonequilibrium spin accumu…
Spin Hall Current Driven by Quantum Interferences in Mesoscopic Rashba Rings
Satofumi Souma, Branislav K. Nikolic
We propose an all-electrical nanoscopic structure where {\em pure} spin current is induced in the transverse voltage probes attached to {\em quantum-coherent} one-dimensional ring…
Mesoscopic Spin Hall Effect in Multiprobe Ballistic Spin-Orbit Coupled Semiconductor Bridges
Branislav K. Nikolic, Liviu P. Zarbo, Satofumi Souma
We predict that unpolarized charge current driven through the longitudinal leads attached to ballistic quantum-coherent two-dimensional electron gas (2DEG) in semiconductor heteros…
