Scanning Tunneling Spectroscopy Study of Three-Dimensional Nanoscale Silicon and Platinum Assemblies in an Opal Matrix

Abstract

Regular systems of Si and Pt nanoclusters have been fabricated in a void sublattice of artificial opal. To incorporate Si into opal voids the thermal CVD technique is used. The samples are filled with Pt from a solution of PtCl(4) in ethanol to fabricate metal contacts to silicon. STM and STS are used to investigate the local electronic behavior of Pt-Si nanostructures. It is shown that Si and Pt are regularly distributed inside the opal voids and form nanoscale metal-semiconductor-metal junctions.
