Bimodal growth of Au on SrTiO3 (001)
We have investigated the vapor phase growth of Au on SrTiO3 (001)-(2x1) substrates by UHV scanning tunneling microscopy. Submonolayer (ML) coverages below 300°C wet the surface as disordered metastable 2D islands. Beyond 0.75 ML fcc nanocrystals with a (111) interface are nucleated and ripen by dewe...
