Mapping electronic states of dual-parallel and symmetric zigzag grain boundaries of graphene on highly oriented pyrolytic graphite
Jun Ma, Xiaying Li, Longjing Yin +7
The grain boundaries (GBs) of a graphene surface were extensively studied because GBs with specific defect configurations result in the formation of new curved structures, which ca…
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…
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…
Magnetic-field-assisted electron confinement and valley splitting in strained graphene
Jun-Fang Liu, Ke-Ke Bai, Jia-Bin Qiao +5
Spatially varying strained graphene can acquire interesting electronic properties because of the strain-induced valley-dependent gauge (pseudomagnetic) fields1,2. Here we report th…
Unveiling the Structural Origin of the High Carrier Mobility of a Molecular Monolayer on Boron Nitride
Rui Xu, Daowei He, Yuhan Zhang +10
Very recently, it was demonstrated that the carrier mobility of a molecular monolayer dioctylbenzothienobenzothiophene (C8-BTBT) on boron nitride can reach 10 cm2/Vs, the highest a…
