"Density Functional Theory (DFT) and identified 32 different 2D vdW dielectrics... 6 promising dielectric candidates introduced for n-MOS Field Effect Transistors (FETs)... rare-earth oxyhalides (HoOI, LaOBr, LaOCl, LaOI, SrI2, and YOBr). Our theoretical study and computational modeling explicitly reveal that these introduced 2D dielectrics with a thickness less than 0.8 nm outperform traditional 3D oxide dielectrics such as HfO2 with a thickness of 10 nm"
