Three-dimensional topological semimetal phase in layered TaNiTe5 probed by de Haas-van Alphen effect
Zheng Chen, Min Wu, Yong Zhang +13
Layered three-dimensional (3D) topological semimetals have attracted intensively attention due to the exotic phenomena and abundantly tunable properties. Here we report the experim…
Large Magnetoresistance in Topological Insulator Candidate TaSe3
Yong Zhang, Tongshuai Zhu, Haijun Bu +11
Large unsaturated magnetoresistance (XMR) with magnitude about 1000% is observed in topological insulator candidate TaSe3 from our high field (up to 38 T) measurements. Two oscilla…
Magneto-transport and Shubnikov-de Haas oscillations in the layered ternary telluride Ta3SiTe6 topological semimetal
Muhammad Naveed, Fucong Fei, Haijun Bu +10
Topological semimetals characterize a novel class of quantum materials hosting Dirac/Weyl fermions. The important features of topological fermions can be exhibited by quantum oscil…
Intrinsic magnetic topological insulator phases in the Sb doped MnBi2Te4 bulks and thin flakes
Bo Chen, Fucong Fei, Dongqin Zhang +23
Magnetic topological insulators (MTIs) offer a combination of topologically nontrivial characteristics and magnetic order and show promise in terms of potentially interesting physi…
First-principles theory of coloration of WO upon charge insertion
Yu Xue, Yong Zhang, Peihong Zhang
We report first-principles investigations of the coloration of WO upon charge insertion, using sodium tungsten bronze (NaWO) as a model system. Our results explain well…
