Growth and morphology of palladium particles epitaxially deposited on a MgO(100) surface

Shapes, multiple twins and surface structures of monodisperse FePt magnetic nanocrystals

“…The faceting is the most favorable mechanism for minimizing particle surface energy. The preparation conditions and techniques, however, significantly influence the shape of the particles [37,38]. At nanometer scale, the most frequently observed shapes are truncated octahedron, cuboctahdron, icosahedron, decahedron and truncated decahedra including star, the round pentagon and the Marks decahedron.…”

STM/TEM comparative study of Pd clusters epitaxially grown on highly oriented pyrolytic graphite

“…These clusters experimental conditions, clusters are growing in (111) epitaxy on the graphite [7]. The most likely facets for high temperature growth of Pd are (111) and (100) [15]. Pd Figure 7 presents a pair of bright field and WBDF images from clusters in a step.…”

HRTEM Studies of the Epitaxial Growth of Pd Particles (1-6 nm) on ZnO Micro-Prisms

“…The samples were The average ratio between the height and the basal diameter of the particles is approximately 0.4, which is the same as in the case of high temperature grown Pd on MgO (100) [1,5].…”

“…Small supported particles used as model catalysts (Pd, Pt, Rh, Cu, Ni), are often prepared by condensation of metal in UHV conditions on oxides single crystals, such as MgO [1], Ti02 [2], Al203 [3]. Among the different techniques of electron microscopy, HRTEM profile imaging is the best method for studying the morphology of the particles and the structure of their interface with the substrate [4,5].…”
