Turgut Yilmaz, Xiao Tong, Zhongwei Dai +8
Dispersionless flat bands are proposed to be a fundamental ingredient to achieve the various sought after quantum states of matter including high-temperature superconductivity1-4 a…
Surface buckling of phosphorene materials: determination, origin and influence on electronic structure
Zhongwei Dai, Wencan Jin, Jie-Xiang Yu +7
The surface structure of phosphorene crystals materials is determined using surface sensitive dynamical micro-spot low energy electron diffraction (μLEED) analysis using a high spa…
Observation of oscillatory relaxation in the Sn-terminated surface of epitaxial rock-salt SnSe topological crystalline insulator
Wencan Jin, Suresh Vishwanath, Jianpeng Liu +20
Topological crystalline insulators have been recently predicted and observed in rock-salt structure SnSe thin films. Previous studies have suggested that the Se-terminate…
