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…
New record of high ZT found in hybrid transition-metal-dichalcogenides
Yulou Ouyang, Yuee Xie, Zhongwei Zhang +2
The search for thermoelectrics with higher figures of merit (ZT) will never stop due to the demand of heat harvesting. Single layer transition metal dichalcogenides (TMD), namely M…
A systematic investigation of thermal conductivities of transition metal dichalcogenides
Zhongwei Zhang, Yuee Xie, Yulou Ouyang +1
The thermal conductivities of MoS2 and WS2 have been reported by some experimental and theoretical studies, however, the results are different from each other. Here, thermal transp…
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…
Phonon transport in single-layer Boron nanoribbons
Zhongwei Zhang, Yuee Xie, Qing Peng +1
Inspired by the successful synthesis of several allotropes, boron sheets have been one of the hottest spot areas of focus in various fields. Here, we study phonon transport in thre…
Transition of thermal rectification in silicon nanocones
Zhongwei Zhang, Yuanping Chen, Yuee Xie +1
Current understanding of thermal rectification asserts that the rectification ratio (R), which measures the relative heat flux between two ends of a nanostructure, is determined by…
Geometry, stability and thermal transport of hydrogenated graphene nanoquilts
Zhongwei Zhang, Yuee Xie, Qing Peng +1
Geometry, stability, and thermal transport of graphene nanoquilts folded by hydrogenation are studied using molecular dynamics simulations. The hydrogenated graphene nanoquilts sho…
