Semi-Dirac Semimetal in Silicene Oxide
Chengyong Zhong, Yuanping Chen, Yuee Xie +2
Semi-Dirac semimetal is a material exhibiting linear band dispersion in one direction and quadratic band dispersion in the orthogonal direction and, therefore, hosts massless and m…
Type-I and type-II Dirac fermions in graphene with nitrogen-molecule line defects
Honghong Zhang, Yuee Xie, Chengyong Zhong +2
Recently, type-II Dirac fermions characterized by strongly titled Dirac cones have been proposed. The new fermions exhibit unique physical properties different from the type-I Dira…
Dirac Nodal Lines and Tilted Semi-Dirac Cones Coexisting in a Striped Boron Sheet
Honghong Zhang, Yuee Xie, Zhongwei Zhang +4
The enchanting Dirac fermions in graphene stimulated us to seek for other two-dimensional (2D) Dirac materials, and boron monolayers may be a good candidate. So far, a number of mo…
Electron and phonon properties and gas storage in carbon honeycomb
Yan Gao, Yuanping Chen, Chengyong Zhong +3
A new kind of three-dimensional carbon allotropes, termed carbon honeycomb (CHC), has recently been synthesized [PRL 116, 055501 (2016)]. Based on the experimental results, a famil…
Coexistence of flat bands and Dirac bands in a carbon-Kagome-lattice family
Chengyong Zhong, Yuee Xie, Yuanping Chen +1
The Dirac bands and flat bands are difficult to coexist because they represent two extreme ends of electronic properties. However, in this paper, we propose a carbon-Kagome-lattice…
Towards Three-Dimensional Weyl-SurfaceSemimetals in Graphene Networks
Chengyong Zhong, Yuanping Chen, Yuee Xie +3
Graphene as a two-dimensional (2D) topological Dirac semimetal has attracted much attention for its outstanding properties and potential applications. However, three-dimensional (3…
