Abstract
Formation of metal nano-islands on heat-treated substrates by either conventional deposition or by electron beam-induced chemical vapour deposition (EBI-CVD) was performed at elevated temperatures in an ultrahigh vacuum transmission electron microscope (UHV-TEM). Pd islands on SrTiO3 (001) substrates, Pd silicide islands on Si (111) substrates, and Fe silicide islands on Si (111) substrates showed bimodal island growth; both substrates blocked islands and nano-wires. The morphologies of these islands are suggested to be sensitive to the substrate conditions because of heat treatment before deposition. Selective growth of the nano-wires was successful in the case of EBI-CVD.
