Creating and probing wide-bandgap nanoribbon-like structures in a continuous metallic graphene sheet
Si-Yu Li, Mei Zhou, Jia-Bin Qiao +2
The light-like dispersion of graphene monolayer results in many novel electronic properties in it1, however, this gapless feature also limits the applications of graphene monolayer…
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…
Spatial variation of energy gap and Landau levels around gapped bilayer graphene domain walls
Long-Jing, Si-Yu Li, Jia-Bin Qiao +2
Bilayer graphene contains, compared to graphene monolayer, an additional graphene sheet and, therefore, extra degrees of freedom, making it a unique system for complex electronic s…
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…
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…
