Gate-independent energy gap in non-covalently intercalated bilayer graphene on SiC(0001)
Yuanchang Li
Our first-principles calculations show that an energy gap around 0.12-0.25 eV can be engineered in epitaxial graphene on SiC(0001) through the non-covalent intercalation of transit…
Unconventional quantized edge transport in the presence of inter-edge coupling in intercalated graphene
Yuanchang Li
It is generally believed that the inter-edge coupling destroys the quantum spin Hall (QSH) effect along with the gap opening at the Dirac points. Using first-principles calculation…
Dirac Fermions in Blue-Phosphorus
Yuanchang Li, Xiaobin Chen
We propose that Dirac cones can be engineered in phosphorene with fourfold-coordinated phosphorus atom. The key is to separate in energy the in-plane (, and ) and out…
Quasi-freestanding monolayer heterostructure of graphene and hexagonal boron nitride on Ir(111) with a chiral boundary
Mengxi Liu, Yuanchang Li, Pengcheng Chen +10
Monolayer lateral heterostructure of graphene and hexagonal boron nitride (h-BNC) has attracted a growing attention mainly due to its tunable band-gap character and unique physical…
Dirac Fermion in Strongly-Bound Graphene Systems
Yuanchang Li, Pengcheng Chen, Gang Zhou +5
It is highly desirable to integrate graphene into existing semiconductor technology, where the combined system is thermodynamically stable yet maintain a Dirac cone at the Fermi le…
