First-Principles Prediction of Intrinsic Ferrovalley Properties in Janus Rare-Earth PrXY (X≠Y=Cl, Br, I) Monolayers

In this work, using first-principles calculations,we predict a promising class of two-dimensional ferromagnetic semiconductors, namely Janus PrXY(X≠Y=Cl,Br,I) monolayers. Through first-principles calculations, we found that PrXY monolayers have excellent dynamic and...
