Researchers have discovered that a phenomenon called interfacial polarization can adjust the surface work function of metallic ruthenium dioxide (RuO2) by more than 1 electron volt (eV), according to a study published in Nature Communications. The work function is a key property that determines how easily electrons can be emitted from a material's surface.
The effect was achieved by creating a thin layer of a different material on the RuO2 surface, causing a tiny atomic shift that alters the electronic structure. This precise control over the work function could lead to advances in catalysis, electronics, and energy devices.
The study, conducted by scientists at [university or lab name if verified], demonstrates a new way to engineer material surfaces at the atomic level. The findings were confirmed through experiments and theoretical calculations.
