Interaction-induced metallic state in graphene on hexagonal boron nitride
Jin-Rong Xu, Ze-Yi Song, Chen-Guang Yuan +1
The Coulomb interaction is widely known to enhance the effective mass of interacting particles and therefore tends to favor a localized state at commensurate filling. Here, we will…
Possible Way to Make MgFeGe a New Fe-based Superconductor
Ming-Cui Ding, Yu-Zhong Zhang
We propose that the contrasting low-temperature behaviors observed experimentally among isostructural and isoelectronic materials, like non-superconducting and nonmagnetic MgFeGe,…
Gate-induced Gap in Bilayer Graphene Suppressed by Coulomb Repulsion
Jin-Rong Xu, Ze-Yi Song, Hai-Qing Lin +1
We investigate the effect of on-site Coulomb repulsion on the band gap of the electrically gated bilayer graphene by employing coherent potential approximation in the paramagne…
Magnetic Properties Controlled by Interstitial or Interlayer Cations in Iron Chalcogenides
Shan-Chang Tang, Ming-Cui Ding, Yu-Zhong Zhang
By applying density functional theory calculations to iron chalcogenides, we find that magnetic order in FeTe and magnetic instability at in KFeSe are c…
