Dual Enhancement of Superconductivity in FeSe/SrTiO3 via Orbital and Correlation Synergy
Guihao Jia, Jingming Yan, Yucong Peng +5
The paper shows that applying tensile strain to monolayer FeSe/SrTiO3 shifts the dz2 orbital toward the Fermi level, first enhancing electronic correlations and then hybridizing wi…
Structural and electronic signatures of strain-tunable marginally twisted bilayer graphene
Pei Ouyang, Jiawei Yu, Qian Li +11
Marginally twisted bilayer graphene having small twist angles is predicted to exhibit unique structural and electronic properties, though experimental characterization remains limi…
Direct Visualization of Room-temperature Stair-stepped Quantum Spin Hall States in Bi4Br4
Zhiqiang Hu, Yuqi Zhang, Yuyang Wang +7
Topological insulators host exotic quantum phenomena such as the quantum spin Hall (QSH) effect, which enables dissipationless one-dimensional edge conduction. Realizing such state…
Lattice-decoupled rotatable stripe-like charge order within the strange metal phase of 2M-WS2
Kebin Xiao, Yunkai Guo, Daran Fu +11
In quantum materials, charge orders typically stabilize in specific crystallographic orientations, though their formation mechanisms may vary. Here, using low-temperature scanning…
Strain and twist angle driven electronic structure evolution in twisted bilayer graphene
Jiawei Yu, Guihao Jia, Qian Li +14
In twisted bilayer graphene (TBG) devices, local strains frequently coexist and intertwine with the twist-angle-dependent moiré superlattice, significantly influencing the electro…
Topological surface states in γ-PtBi evidenced by scanning tunneling microscopy
Yunkai Guo, Jingming Yan, Wen-Han Dong +11
For the application of topological materials, the specific location of their topological surface states with respect to the Fermi level are important. γ-PtBi2 has been demonstrate…
