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...
2005Vol.43No.1pp.169-174DOI: Polaronic Effects of an Exciton in a Cylindrical Quantum Wire WANG Rui-Qiang, XIE Hong-Jing, GUO Kang-Xian, YU You-Bin, andDENG Yong-Qing De...
期刊信息 篇名 Influence of an external voltage on the conductance through a quantum dot side-coupled to a short quantum wire 语种 英文 撰写或编译 撰写 作者 张志勇 第一作者单位 南京大学物理系 刊物名称 Journal of Physics: Condensed Matter 页面...
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...
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...
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...
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 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...
