Gate-Tunable Exchange Coupling Between Cobalt Clusters on Graphene
Hua Chen, Qian Niu, Zhenyu Zhang +1
We use spin-density-functional theory (SDFT) ab initio calculations to theoretically explore the possibility of achieving useful gate control over exchange coupling between cobalt…

Optimization of Mn Doping in Group-IV-based Dilute Magnetic Semiconductors by Electronic Co-dopants
Hua Chen, Wenguang Zhu, Efthimios Kaxiras +1
The percentage of substitutional doping of magnetic atoms (Mn) in group-IV-based dilute magnetic semiconductors (DMS) can be increased by co-doping with another conventional electr…
