WebSep 3, 2024 · In this work, we predict that Ta2M3Te5 (M\u2009=\u2009Pd, Ni) monolayers can be 2D QTIs with second-order topology due to the double-band inversion. A time-reversal-invariant system with two mirror reflections (Mx and My) can be classified by Stiefel-Whitney numbers (w1,\u2009w2) due to the combined symmetry TC2z. WebFIG. 1. (color online).
