Quadrupole topological insulators in Ta2 M 3Te5 (M = Ni, Pd) monolayers
Abstract Higher-order topological insulators have been introduced in the precursory Benalcazar-Bernevig-Hughes quadrupole model, but no electronic compound has been proposed to be a quadrupole topological insulator (QTI) yet. In this work, we predict that Ta2 M 3Te5 (M = Pd, Ni) monolayers can be 2D...
