Abstract:Two-dimensional (2D) metal oxides have broad prospective applications in the fields of catalysis, electronic devices, sensors, and detectors. However, non-van der Waals 2D metal oxides have rarely been studied because they are hard to peel off or synthesize. In this work, taking alumina (Al2O3) as a typical representative of 2D boron group oxides, the structural stability and electrical properties of 2D Al2O3 are investigated through first-principles calculations. The thinnest Al2O3 structure is a bilayer, and… Show more
