Linear magnetoresistance caused by mobility fluctuations in the n-doped Cd3As2
A. Narayanan, M. D. Watson, S. F. Blake +10
Cd3As2 is a candidate three-dimensional Dirac semi-metal which has exceedingly high mobility and non-saturating linear magnetoresistance that may be relevant for future practical a…
Half-Heusler topological insulators
Binghai Yan, Anne de Visser
Ternary semiconducting or metallic half-Heusler compounds with an atomic composition 1:1:1 are widely studied for their flexible electronic properties and functionalities. Recently…
Topological nature and the multiple Dirac cones hidden in Bismuth high-Tc superconductors
Gang Li, Binghai Yan, Ronny Thomale +1
Recent theoretical studies employing density-functional theory have predicted BaBiO (when doped with electrons) and YBiO to become a topological insulator (TI) with a l…
Stacking-dependent energetics and electronic structure of ultrathin polymorphic VVI topological insulator nanofilms
Can Li, Torben Winzer, Aron Walsh +3
Topological insulators represent a paradigm shift in surface physics. The most extensively studied BiSe-type topological insulators exhibit layered structures, wherein neig…
New Family of Robust 2D Topological Insulators in van der Waals Heterostructures
Liangzhi Kou, Shu-Chun Wu, Claudia Felser +3
We predict a new family of robust two-dimensional (2D) topological insulators in van der Waals heterostructures comprising graphene and chalcogenides BiTeX (X=Cl, Br and I). The la…
Evidence of surface transport and weak anti-localization in single crystal of Bi2Te2Se topological insulator
Chandra Shekhar, C. E. Viol Barbosa, Binghai Yan +4
Topological insulators are known to their metallic surface states, a result of strong-spin-orbital coupling, that show unique surface transport phenomenon. But these surface transp…
