Abstract
- Pd crystals grown in ultrahigh vacuum (UHV) on nanostructured SrTiO3(001) and anatase TiO2(001) thin film substrates were studied using scanning tunneling microscopy. The crystals have the equilibrium shape of a truncated octahedron with a {111} top facet, {111} and {001} side facets, and a {111} interface. A consistent crystal shape is reached only after annealing the samples in UHV at 450 °C or above. By measuring the top facet dimensions of the equilibrium crystals, we determine the ratio of the surface energies for Pd to be γ 111 / γ 001 = 0.77 ± 0.02. [ABSTRACT FROM AUTHOR]
