Electronic confinement in quantum dots of twisted bilayer graphene
Xiao-Feng Zhou, Yi-Wen Liu, Hong-Yi Yan +3
Electronic properties of quantum dots (QDs) depend sensitively on their parent materials. Therefore, confined electronic states in graphene QDs (GQDs) of monolayer and Bernal-stack…
Tunable lattice reconstruction and bandwidth of flat bands in magic-angle twisted bilayer graphene
Yi-Wen Liu, Ying Su, Xiao-Feng Zhou +10
The interplay between interlayer van der Waals interaction and intralayer lattice distortion can lead to structural reconstruction in slightly twisted bilayer graphene (TBG) with t…
Breaking whispering-gallery modes of massless Dirac fermions in graphene quantum dots by Coulomb interaction
Zhong-Qiu Fu, Ke-Ke Bai, Ya-Ning Ren +2
Coulomb interaction is of central importance in localized energy levels (bound states) or electronic flat bands and could result in many exotic quantum phases, such as magnetic, su…
Scanning tunneling microscope characterizations of a circular graphene resonator realized with p-p junctions
Ya-Ning Ren, Jiao-Jiao Zhou, Zhong-Qiu Fu +11
Using low-temperature high-magnetic-field scanning tunneling microscopy and spectroscopy (STM/STS), we systematically study a graphene quantum dot (GQD) defined by a circular graph…
Relativistic Artificial Molecules Realized by Two Coupled Graphene Quantum Dots
Zhong-Qiu Fu, Yue-Ting Pan, Jiao-Jiao Zhou +6
Coupled quantum dots (QDs), usually referred to as artificial molecules, are important not only in exploring fundamental physics of coupled quantum objects, but also in realizing a…
Spatial Confinement, Magnetic Localization and Their Interactions on Massless Dirac Fermions
Zhong-Qiu Fu, Yu Zhang, Jia-Bin Qiao +8
It is of keen interest to researchers understanding different approaches to confine massless Dirac fermions in graphene, which is also a central problem in making electronic device…
Segregation growth and self-organization of ordered S atomic superlattices confined at interface between graphene and substrates
Dong-Lin Ma, Zhong-Qiu Fu, Ke-Ke Bai +7
Ordered atomic-scale superlattices on surface hold great interest both for basic science and for potential applications in advanced technology. However, controlled fabrication of s…
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…
