摘要：

In this paper, copper deposition on platinum stepped single crystals (Pt(332), Pt(665)) and Pt(111) has been respectively investigated by CV and EC-STM. It is shown that the feature of Cu UPD is functional to the step density, indicative of the increase in amplitude of the quasi-reversible peaks at 0.4 V with increase of step density.
