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…
Electric-field switching of exciton spin splitting in coupled quantum dots
Xiaojing Li, Kai Chang
We investigate theoretically the spin splitting of the exciton states in semiconductor coupled quantum dots (CQDs) containing a single magnetic ion. We find that the spin splitting…
Resonant Tunneling through double-bended Graphene Nanoribbons
Z. Z. Zhang, Kai Chang, K. S. Chan
We investigate theoretically resonant tunneling through double-bended graphene nanoribbon structures, i.e., armchair-edged graphene nanoribbons (AGNRs) in between two semi-infinite…
Tuning of energy levels and optical properties of graphene quantum dots
Z. Z. Zhang, Kai Chang, F. M. Peeters
We investigate theoretically the magnetic levels and optical properties of zigzag- and armchair-edged hexagonal graphene quantum dots (GQDs) utilizing the tight-binding method. A n…
Anisotropic spin transport in two-terminal mesoscopic rings: the Rashba and Dresselhaus spin-orbit interactions
M. Wang, Kai Chang
We investigate theoretically the spin transport in two-terminal mesoscopic rings in the presence of both the Rashba spin-orbit interaction (RSOI) and the Dresselhaus spin-orbit int…
