Article Synopsis
- The rearrangement of surface atoms in oxide nanocrystals, specifically tungsten trioxide, significantly enhances their physical and chemical properties.
- Direct investigation using a scanning transmission electron microscope reveals that the surface atoms form a (1 × 2) structure and that density functional theory (DFT) calculations support these findings.
- The study also uncovers that surface reconstruction leads to a shift in the Fermi level towards the conduction band, akin to n-type doping, and may offer a novel approach to repair sub-nanometer cracks in tungsten trioxide.
