Orbital hybridization in graphene-based artificial atoms
Yue Mao, Hui-Ying Ren, Xiao-Feng Zhou +6
Intraatomic orbital hybridization and interatomic bond formation are the two fundamental processes when real atoms are condensed to form matter. Artificial atoms mimic real atoms b…
Realization of 2/3-layer transition metal dichalcogenides
Ya-Xin Zhao, Zi-Yi Han, Ya-Ning Ren +4
Layered van der Waals transition metal dichalcogenides (TMDCs), generally composed of three atomic X-M-X planes in each layer (M = transition metal, X = chalcogen), provide versati…
Visualizing orbital angular momentum induced single wavefront dislocation in graphene
Yi-Wen Liu, Yu-Chen Zhuang, Ya-Ning Ren +5
Phase singularities are phase-indeterminate points where wave amplitudes are zero, which manifest as phase vertices or wavefront dislocations. In the realm of optical and electron…
Relativistic artificial molecules with tunable coupling and orbitals
Xiao-Feng Zhou, Yu-Chen Zhuang, Mo-Han Zhang +3
In a molecule formed by two atoms, energy difference between bonding and antibonding orbitals should depend on distance of the two atoms. However, exploring molecular orbitals of t…
Tunable interfacial chemisorption with atomic-level precision in a graphene WSe2 heterostructure
Mo-Han Zhang, Fei Gao, Aleksander Bach Lorentzen +7
It has long been an ultimate goal to introduce chemical doping at the atomic level to precisely tune properties of materials. Two-dimensional materials have natural advantage becau…
Coexistence of Reconstructed and Unreconstructed Structures in Structural Transition Regime of Twisted Bilayer Graphene
Xiao-Feng Zhou, Yi-Wen Liu, Chen-Yue Hao +7
In twisted bilayer graphene (TBG), a twist-angle-dependent competition between interlayer stacking energy and intralayer elastic energy results in flat rigid layers at large twist…
Stabilizing sample-wide Kekulé orders in graphene/transition metal dichalcogenide heterostructures
Mo-Han Zhang, Ya-Ning Ren, Qi Zheng +2
Kekulé phases are Peierls-like lattice distortions in graphene that are predicted to host novel electronic states beyond graphene (1-8). Although the Kekulé phases are realized in…
Tunable Sample-wide Electronic Kagome Lattice in Low-angle Twisted Bilayer Graphene
Qi Zheng, Chen-Yue Hao, Xiao-Feng Zhou +3
Overlaying two graphene layers with a small twist angle can create a moire superlattice to realize exotic phenomena that are entirely absent in graphene monolayer. A representative…
Electronic confinement in quantum dots of twisted bilayer graphene
Xiao-Feng Zhou, Yi-Wen Liu, Hong-Yi Yan +3
Electronic properties of quantum dots (QDs) depend sensitively on their parent materials. Therefore, confined electronic states in graphene QDs (GQDs) of monolayer and Bernal-stack…
Oscillations of van Hove singularities spacing induced by sub-Angstrom fluctuations of interlayer spacing in graphene superlattices
Ya-Xin Zhao, Xiao-Feng Zhou, Yu Zhang +1
Physical properties of two-dimensional van der Waals (vdWs) structures depend sensitively on both stacking orders and interlayer interactions. Yet, in most cases studied to date, t…
Tunable lattice reconstruction and bandwidth of flat bands in magic-angle twisted bilayer graphene
Yi-Wen Liu, Ying Su, Xiao-Feng Zhou +10
The interplay between interlayer van der Waals interaction and intralayer lattice distortion can lead to structural reconstruction in slightly twisted bilayer graphene (TBG) with t…
