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…
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…
