Dirac equation description on the electronic states and magnetic properties of a square graphene quantum dot
Changlin Tang, Weihua Yan, Yisong Zheng +2
Electronic eigen-states of a square graphene quantum dot(GQD) terminated by both zigzag and armchair edges are derived in the theoretical framework of Dirac equation. We find that…
Spin-dependent electron transport through a parallel double-quantum-dot structure
Weijiang Gong, Yisong Zheng
Electron transport properties in a parallel double-quantum-dot structure with three-terminals are theoretically studied. By introducing a local Rashba spin-orbit coupling, we find…
Contact conductance between graphene and quantum wires
Haidong Li, Yisong Zheng
The contact conductance between graphene and two quantum wires which serve as the leads to connect graphene and electron reservoirs is theoretically studied. Our investigation indi…
Tunable pure spin currents in a triple-quantum-dot ring
Weijiang Gong, Yisong Zheng, Tianquan Lv
Electron transport properties in a triple-quantum-dot ring with three terminals are theoretically studied. By introducing local Rashba spin-orbit interaction on an individual quant…
Suppressed conductance in a metallic graphene nano-junction
Haidong Li, Lin Wang, Yisong Zheng
The linear conductance spectrum of a metallic graphene junction formed by interconnecting two gapless graphene nanoribbons is calculated. A strong conductance suppression appears i…
