ECSTM tip-induced nanostructuring of ordered Pd clusters array

Abstract

Electrochemical scanning tunnelling fnicroscope(ECSTM) was used to induce local electrodeposition under mild electrochemical and tunnelling bias conditions. The Pd nanocluster arrays were fabricated on Au(111) in PdCl2 and PdSO4 solutions respectively and different parameters for nanostructructuring were explored in the corresponding solutions.
