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…
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…
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…
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…
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…
