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…
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…
