Selecting the shape of supported metal nanocrystals: Pd huts, hexagons, or pyramids on SrTiO3(001).

Increasing interest in oxide supported nanoparticle science and technology is stimulating research into controlling nanocrystal shape. Pd forms nanocrystals on the surface of SrTiO3(001), and depending on the crystallographic interface of the Pd with the substrate three shapes can be created: trunca...
