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…
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…
Evolution of electronic structure in pristine and hole-doped kagome metal RbVSb
Jiawei Yu, Kebin Xiao, Yonghao Yuan +8
We report on in situ low-temperature (4 K) scanning tunneling microscope measurements of atomic and electronic structures of the cleaved surfaces of an alkali-based kagome metal Rb…
Atomic-scale visualization of d-wave altermagnetism
Daran Fu, Liu Yang, Yi Shen +7
Altermagnetism is a newly identified magnetic phase, distinct from conventional ferromagnetism and antiferromagnetism. It exhibits no net magnetization while breaking time-reversal…
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…
