Topological phases in TaRhTe4: from monolayer to bulk — •Xiao Zhang — Leibniz Institute for Solid State and Material Research, Dresden, Germany
Topological phases are studied in different dimensional TaRhTe4 using the method of density functional theory (DFT). We find that bulk TaRhTe4 is a Weyl semimetal, whereas both monolayer and bilayer TaRhTe4 display features of quantum spin Hall (QSH) insulator. A complete phase diagram linking monolayer, bilayer, and bulk TaRhTe4 is obtained by varying intra- and inter-bilayer distance of the three-dimensional structure. It contains phases of Weyl semimetal, weak topological insulator, and normal insulator.
