Spin Accumulation in a Quantum Wire with Rashba Spin-Orbit Coupling
Spin Accumulation Rashba Spin-Orbit Coupling Quantum Wire
2009/9/4
We investigate theoretically the spin accumulation in a Rashba spin-orbit coupling quantum wire. Using the scattering matrix approach within the effective free-electron approximation, we have demonstr...

Hydrogenic Impurity in Ridge Quantum Wire
Hydrogenic impurity Binding energy V-groove quantum wire
2010/10/13
The binding energies as well as wave functions of hydrogenic impurities located in V-groove
GaAs=AlxGa1¡xAs quantum wires are calculated for different positions of the impurity inside the wires...
On Electron Mobility in a Rectangular Quantum Wire due to Alloy Disorder
Electron Mobility Alloy Disorder Rectangular Quantum Wire
2010/4/12
Analytic expressions are derived to describe the electron mobility and relaxation rate in the rectangular quantum wire experiencing scattering due to alloy disorder. The dependence of electron mobilit...
Short-range Correlations in Coupled Quantum-wire Systems
Short-range Correlations Coupled Quantum-wire Systems
2010/4/13
We study the contact values of the inter-wire pair-correlation function in electron-electron and electron-hole double-wire systems. For this purpose the ladder approximation as generalized to multicom...
Effects of disorder on the drag rate in double quantum-wire systems
drag rate double quantum-wire systems
2010/4/15
We study the Coulomb drag rate for electrons in a double quantum-wire structure in the presence of disorder. We use the particle number-conserving relaxation-time approximation to phenomenologically b...
The Effect of Spatially Dependent Screening On the Donor Ionization Energy in a Quantum Wire
Donor Ionization Energy Quantum Wire
2010/4/16
The effect of the spatially dependent screening on the ionization energy of a shallow donor in a 1D quantum well wire made of Ga1-xAlx/GaAs superlattice is presented. A variational approach is used to...
