Direct imaging of topological edge states at a bilayer graphene domain wall
Long-Jing Yin, Hua Jiang, Jia-Bin Qiao +1
The AB-BA domain wall in gapped graphene bilayers is a rare naked structure hosting topological electronic states. Here we show, for the first time, direct imaging of its topologic…
Experimental Observation of Surface States and Landau Levels Bending in Bilayer Graphene
Long-Jing Yin, Yu Zhang, Jia-Bin Qiao +2
We report on microscopic measurements of the low-energy electronic structures both at zigzag and armchair edges of bilayer graphene using scanning tunneling microscopy and spectros…
Detecting giant electron-hole asymmetry in graphene monolayer generated by strain and charged-defect scattering via Landau level spectroscopy
Ke-Ke Bai, Yi-Cong Wei, Jia-Bin Qiao +5
The electron-hole symmetry in graphene monolayer, which is analogous to the inherent symmetric structure between electrons and positrons of the Universe, plays a crucial role in th…
Observation of Valley-polarized Landau Levels in Strained Graphene
Si-Yu Li, Ke-Ke Bai, Long-Jing Yin +3
In strained graphene, lattice deformation can create pseudo-magnetic fields and result in zero-field Landau level-like quantization. In the presence of an external magnetic field,…
Atomic resolution imaging of the two-component Dirac-Landau levels in a gapped graphene monolayer
Wen-Xiao Wang, Long-Jing Yin, Jia-Bin Qiao +6
The wavefunction of massless Dirac fermions is a two-component spinor. In graphene, a one-atom-thick film showing two-dimensional Dirac-like electronic excitations, the two-compone…
Landau Quantization and Fermi Velocity Renormalization in Twisted Graphene Bilayers
Long-Jing Yin, Jia-Bin Qiao, Wei-Jie Zuo +5
Currently there is a lively discussion concerning Fermi velocity renormalization in twisted bilayers and several contradicted experimental results are reported. Here we study elect…
Experimental evidence for non-Abelian gauge potentials in twisted graphene bilayers
Long-Jing Yin, Jia-Bin Qiao, Wei-Jie Zuo +2
The methods for realizing of non-Abelian gauge potentials have been proposed in many different systems in condensed matter1-5. The simplest realization among them may be in a graph…
Spatially resolving unconventional interface Landau quantization in a graphene monolayer-bilayer planar junction
Wei Yan, Si-Yu Li, Long-Jing Yin +3
Graphene hybrid planar structures consisting of two regions with different quantum Hall (QH) states exhibit unusual transport properties1-5, originating from chiral edge states equ…
Landau Quantization in Graphene Monolayer, Bernal Bilayer, and Bernal Trilayer on Graphite Surface
Long-Jing Yin, Si-Yu Li, Jia-Bin Qiao +2
Electronic properties of surface areas decoupled from graphite are studied using scanning tunnelling microscopy and spectroscopy. We show that it is possible to identify decoupled…
