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…

Generating nanoscale and atomically-sharp p-n junctions in graphene via monolayer-vacancy-island engineering of Cu surface
Ke-Ke Bai, Jiao-Jiao Zhou, Yi-Cong Wei +5
Creation of high quality p-n junctions in graphene monolayer is vital in studying many exotic phenomena of massless Dirac fermions. However, even with the fast progress of graphene…
