Tailoring interfacial nanostructures at graphene/transition metal dichalcogenide heterostructures
Ya-Ning Ren, Mo-Han Zhang, Qi Zheng +1
Integration of two-dimensional (2D) van der Waals (vdWs) materials with non-2D materials to realize mixed-dimensional heterostructures has potential for creating functional devices…
Experimental evidence for electron-electron interaction and spin-charge separation in graphene quantum dots
Hui-Ying Ren, Ya-Ning Ren, Qi Zheng +2
Graphene quantum dots (GQDs) can exhibit a range of spectacular phenomena such as the Klein-tunneling-induced quasibound states1-6 and Berry-phase-tuned energy spectra7-15. Accordi…
Mixed-dimensional moiré systems of graphitic thin films with a twisted interface
Dacen Waters, Ellis Thompson, Esmeralda Arreguin-Martinez +7
Moiré patterns formed by stacking atomically-thin van der Waals crystals with a relative twist angle can give rise to dramatic new physical properties. The study of moiré materials…
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…
Molecular Collapse States in Elliptical Graphene/WSe2 Heterostructure Quantum Dots
Qi Zheng, Yu-Chen Zhuang, Ya-Ning Ren +3
In relativistic physics, both atomic collapse in heavy nucleus and Hawking radiation in black hole are predicted to occur through Klein tunneling process that couples particles and…
Gate-tunable anomalous Hall effect in a 3D topological insulator/2D magnet van der Waals heterostructure
Vishakha Gupta, Rakshit Jain, Yafei Ren +8
We demonstrate advantages of samples made by mechanical stacking of exfoliated van der Waals materials for controlling the topological surface state of a 3-dimensional topological…
Topological Corner States in Graphene by Bulk and Edge Engineering
Junjie Zeng, Chen Chen, Yafei Ren +3
Two-dimensional higher-order topology is usually studied in (nearly) particle-hole symmetric models, so that an edge gap can be opened within the bulk one. But more often deviates…
Magnetic field-tunable valley-contrasting pseudomagnetic confinement in graphene
Ya-Ning Ren, Yu-Chen Zhuang, Qing-Feng Sun +1
Introducing quantum confinement has uncovered a rich set of interesting quantum phenomena and allows one to directly probe the physics of confined (quasi-)particles. In most experi…
Second-Order Topological Insulator in van der Waals Heterostructures of CoBr/PtHgSe/CoBr
Zheng Liu, Yafei Ren, Yulei Han +2
Second-order topological insulator, which has (d-2)-dimensional topological hinge or corner states, has been observed in three-dimensional materials, but has yet not been observed…
