The dual topological phases in X3AsTe4 (X = Zr, Hf) monolayers.
The quantum anomalous Hall effect (QAHE) and the quantum spin Hall effect (QSHE) hold great potential for advancing next-generation low-power, high-ruggedness electronic and quantum devices. Here, using first-principles calculations, we investigate the interplay between magnetic order and band topology in the two-dimen...
