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…
Interfacial superconductivity and a Se-vacancy ordered insulating phase in the FeSe/PbOx heterostructures
Yunkai Guo, Xuanyu Long, Jingming Yan +3
The discovery of high-temperature superconductivity in FeSe/SrTiO3 has sparked significant interests in exploring new superconducting systems with engineered interfaces. Here, usin…
