Spin Bias Measurement Based on a Quantum Point Contact
Yanxia Xing, Qing-feng Sun, Jian Wang
Electron charge transport through a quantum point contact (QPC) driven by an asymmetric spin bias is studied. A large charge current is induced when the transmission coefficient of…
Influence of dephasing process on the quantum Hall effect and the spin Hall effect
Yanxia Xing, Qing-feng Sun, Jian Wang
We study the influence of the phase relaxation process on Hall resistance and spin Hall current of a mesoscopic two-dimensional (2D) four-terminal Hall cross-bar with or without Ra…
A variant transfer matrix method suitable for transport through multi-probe systems
Z. H. Qiao, J. Wang
We have developed a variant transfer matrix method that is suitable for transport through multi-probe systems. Using this method, we have numerically studied the quantum spin Hall…
Quantum inductance and negative electrochemical capacitance at finite frequency
J. Wang, B. G. Wang, H. Guo
We report on theoretical investigations of frequency dependent quantum capacitance. It is found that at finite frequency a quantum capacitor can be characterized by a classical RLC…
