Giant Spin-Orbit-Induced Spin Splitting in Bi Chains on GaAs(110)
Hyun-Jung Kim, Jun-Hyung Cho
The search for one-dimensional electron systems with a giant Rashba-type spin splitting is of importance for the application of spin transport. Here we report, based on a first-pri…
Contrasting interedge superexchange interactions of graphene nanoribbons embedded in h-BN and graphane
Sun-Woo Kim, Hyun-Jung Kim, Jin-Ho Choi +2
Based on first-principles density-functional theory calculations, we present a comparative study of the elec- tronic structures of ultranarrow zigzag graphene nanoribbons (ZGNRs) e…
Black Phosphorus Nanoelectromechanical Resonators Vibrating at Very High Frequencies
Zenghui Wang, Hao Jia, Xuqian Zheng +6
We report on experimental demonstration of a new type of nanoelectromechanical resonators based on black phosphorus crystals. Facilitated by a highly efficient dry transfer techniq…
Equivalence of Electronic and Mechanical Stresses in Structural Phase Stabilization: A Case Study of Indium Wires on Si(111)
Sun-Woo Kim, Hyun-Jung Kim, Fangfei Ming +4
It was recently proposed that the stress state of a material can also be altered via electron or hole doping, a concept termed electronic stress (ES), which is different from the t…
Quantum Anomalous Hall Effect in Graphene Proximity Coupled to an Antiferromagnetic Insulator
Zhenhua Qiao, Wei Ren, Hua Chen +4
We propose realizing the quantum anomalous Hall effect by proximity coupling graphene to an antiferromagnetic insulator that provides both broken time-reversal symmetry and spin-or…
