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…
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…
Twisted bilayer zigzag-graphene nanoribbon junctions with tunable edge states
Dongfei Wang, De-Liang Bao, Qi Zheng +14
Stacking two-dimensional layered materials such as graphene and transitional metal dichalcogenides with nonzero interlayer twist angles has recently become attractive because of th…
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…
Imaging field-tuned quantum Hall broken-symmetry orders and quantum Hall conducting channel in charge-neutral graphene WSe2 heterostructure
Qi Zheng, Mo-Han Zhang, Ya-Ning Ren +1
The zeroth Landau level (0LL) in graphene has emerged as a flat-band platform in which distinct many-body phases can be explored with unprecedented control by simply tuning the str…
Coexistence of electron whispering-gallery modes and atomic collapse states in graphene WSe2 heterostructure quantum dots
Qi Zheng, Yu-Chen Zhuang, Qing-Feng Sun +1
The relativistic massless charge carriers with a Fermi velocity of about c300 in graphene enable us to realize two distinct types of resonances (c, the speed of light in vacuum). O…
