(Color online) Schematic view of the experimental MS-LECBD setup used for the preparation of nanoparticle thin films.
(Color online) (a) TEM images of a Pt + CoPt particle sample. (b) Same images as in (a) with clusters colored according to their projected area: particles in red correspond to the first peak of the size histogram (c), i.e., CoPt particles, while those in green correspond to the larger particles, i.e., Pt particles and a few multimers (touching particles, partially coalesced). (d) Histogram of edge-to-edge nearest-neighbor distances for CoPt and Pt pairs.
TEM images of several “bunches” of 1.8 nm diameter CoPt clusters.
(a) TEM image of a cluster island obtained from 3.7 nm diameter CoPt cluster deposition on HOPG. (b) Particle size histogram (projected area): While large particles have been formed by coalescence of several incident clusters, a peak corresponding to the incident particles can still be detected.
TEM image of ramified islands obtained from 5.8 nm diameter CoPt cluster deposition on HOPG.
