Contrasting Behavior of Carbon Nucleation in the Initial Stages of Graphene Epitaxial Growth on Stepped Metal Surfaces
Hua Chen, Wenguang Zhu, Zhenyu Zhang
Using first-principles calculations within density functional theory, we study the energetics and kinetics of carbon nucleation in the early stages of epitaxial graphene growth on…

Quasiparticle tunneling in the Moore-Read fractional quantum Hall State
Hua Chen, Zi-Xiang Hu, Kun Yang +2
In fractional quantum Hall systems, quasiparticles of fractional charge can tunnel between the edges at a quantum point contact. Such tunneling (or backscattering) processes contri…

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…
