Charge pumping in monolayer graphene driven by a series of time-periodic potentials
Zhenhua Wu, J. Li, K. S. Chand
We applied the Floquet scattering-matrix formalism to studying the electronic transport properties in a mesoscopic Dirac system. Using the method, we investigate theoretically quan…
Direct detection of the relative strength of Rashba and Dresselhaus spin-orbit interaction: Utilizing the SU(2) symmetry
Jun Li, Kai Chang
We propose a simple method to detect the relative strength of Rashba and Dresselhaus spin-obit interactions in quantum wells (QWs) without relying on the directional-dependent phys…
Electric field driven quantum phase transition between band insulator and topological insulator
Jun Li, Kai Chang
We demonstrate theoretically that electric field can drive a quantum phase transition between band insulator to topological insulator in CdTe/HgCdTe/CdTe quantum wells. The numeric…
D'yakonov-Perel' spin relaxation in InSb/AlInSb quantum wells
Jun Li, Kai Chang, F. M. Peeters
We investigate theoretically the D'yakonov-Perel' spin relaxation time by solving the eight-band Kane model and Poisson equation self-consistently. Our results show distinct behavi…
Spin states in InAs/AlSb/GaSb semiconductor quantum wells
Jun Li, Wen Yang, Kai Chang
We investigate theoretically the spin states in InAs/AlSb/GaSb broken-gap quantum wells by solving the Kane model and the Poisson equation self-consistently. The spin states in InA…
Anomalous Rashba spin-orbit interaction in InAs/GaSb quantum wells
J. Li, Kai Chang, G. Q. Hai +1
We investigate theoretically the Rashba spin-orbit interaction in InAs/GaSb quantum wells(QWs). We find that the Rashba spin-splitting (RSS) depends sensitively on the thickness of…
