Dirac node lines in pure alkali earth metals
Ronghan Li, Xiyue Cheng, Hui Ma +5
Beryllium is a simple alkali earth metal, but has been the target of intensive studies for decades because of its unusual electron behaviors at surfaces. Puzzling aspects include (…
Combined Fast Reversible Liquid-like Elastic Deformation with Topological Phase Transition in NaBi
Xiyue Cheng, Ronghan Li, Dianzhong Li +2
By means of first-principles calculations, we identified the structural phase transition of NaBi from hexagonal ground state to cubic 16 phase above 0.8 GPa, in agreement w…
Topological Metal of NaBi with Ultralow Lattice Thermal Conductivity and Electron-phonon Superconductivity
Xing-Qiu Chen, Ronghan Li, Yan Sun +3
By means of first-principles and \emph{ab initio} tight-binding calculations, we found that the compound of NaBi is a three-dimensional non-trivial topological metal. Its topologic…
Effects of dilute substitutional solutes on carbon in -Fe: interactions and associated carbon diffusion from first-principles calculations
Peitao Liu, Weiwei Xing, Xiyue Cheng +3
By means of first-principles calculations coupled with the kinetic Monte Carlo simulations, we have systematically investigated the effects of dilute substitutional solutes on the…
The three-dimensional topological Dirac semimetal NaBi: the ground state phase
Xiyue Cheng, Ronghan Li, Xing-Qiu Chen +2
By means of first-principles calculations, we found that the early characterized three-dimensional topological bulk Dirac semimetal of the 6/ NaBi is dynamically un…
Interstitial-Boron Solution Strengthened WB
Xiyue Cheng, Wei Zhang, Xing-Qiu Chen +8
By means of variable-composition evolutionary algorithm coupled with density functional theory and in combination with aberration-corrected high-resolution transmission electron mi…
