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…
Enhanced van der Waals epitaxy via electron transfer-enabled interfacial dative bond formation
Weiyu Xie, Toh-Ming Lu, Gwo-Ching Wang +2
Enhanced van der Waals (vdW) epitaxy of semiconductors on layered vdW substrate is identified as the formation of dative bonds. For example, despite that NbSe2 is a vdW layered mat…
Universal stability of two-dimensional traditional semiconductors
Michael C. Lucking, Weiyu Xie, Duk-Hyun Choe +3
Interest in two dimensional materials has exploded in recent years. Not only are they studied due to their novel electronic properties, such as the emergent Dirac Fermion in graphe…
Chalcogenide Perovskites- an Emerging Class of Ionic Semiconductors
Samanthe Pereraa, Haolei Huia, Chuan Zhao +11
We report the synthesis and characterization of a novel class of ionic semiconductor materials- inorganic chalcogenide perovskites. Several different compounds including BaZrS3, Ca…
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…
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…
Band alignment of two-dimensional lateral heterostructures
Junfeng Zhang, Weiyu Xie, Jijun Zhao +1
Recent experimental synthesis of two-dimensional (2D) heterostructures opens a door to new opportunities in tailoring the electronic properties for novel 2D devices. Here, we show…
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…
