Magnetic-field-controlled negative differential conductance in graphene npn junction resonators
Si-Yu Li, Haiwen Liu, Jia-Bin Qiao +2
Negative differential conductance (NDC), characterized by the decreasing current with increasing voltage, has attracted continuous attention for its various novel applications. The…
The tunnelling spectra of quasi-free-standing graphene monolayer
Si-Yu Li, Ke-Ke Bai, Wei-Jie Zuo +7
With considering the great success of scanning tunnelling microscopy (STM) studies of graphene in the past few years, it is quite surprising to notice that there is still a fundame…
Scanning tunneling microscopy and spectroscopy of nanoscale twisted bilayer graphene
Wen-Xiao Wang, Hua Jiang, Yu Zhang +5
Nanoscale twisted bilayer graphene (TBG) is quite instable and will change its structure to Bernal (or AB-stacking) bilayer with a much lower energy. Therefore, the lack of nanosca…
Landau quantization of Dirac fermions in graphene and its multilayer
Long-jing Yin, Ke-ke Bai, Wen-xiao Wang +3
When electrons are confined in a two dimensional (2D) system, typical quantum mechanical phenomena such as Landau quantization can be detected. Graphene systems, including the sing…
Imaging the dynamics of individual hydrogen atom intercalated between two graphene sheets
Wen-Xiao Wang, Yi-Wen Wei, Si-Yu Li +4
The interlayer gallery between two adjacent sheets of van der Waals materials is expected to modify properties of atoms and molecules confined at the atomic interfaces. Here, we di…
Evidence of electron-electron interactions around Van Hove singularities of a graphene Moiré superlattice
Si-Yu Li, Ke-Qin Liu, Long-Jin Yin +7
A variety of new and interesting correlated states have been predicted in graphene monolayer doped to Van Hove singularities (VHSs) of its density-of-state (DOS). However, tuning t…
