Aluminum oxide's irregular atomic surface explains its low reactivity
Researchers at Vienna University of Technology have discovered that the surface of aluminum oxide is irregular at the atomic scale, which explains its low reactivity. The team used noncontact atomic force microscopy to image the surface and found that it is rough and inhomogeneous, with local height variations spanning several atomic layers. This discovery has significant implications for understanding the chemical behavior of materials and could impact various technological applications.
- ▪Aluminum oxide's surface is irregular at the atomic scale, which affects its chemical properties.
- ▪The surface is rough and inhomogeneous, with local height variations spanning several atomic layers.
- ▪The discovery was made using noncontact atomic force microscopy and density functional theory calculations.
