The authors have observed the initial oxidation stages of Cu(001) thin films by in situ ultrahigh vacuum-transmission electron microscopy, examining the role of surface defects, such as surface steps, as possible nucleation sites for the Cu{sub 2}O on Cu(001) due to oxidation. Weak beam techniques were used to image surface steps. In contrast to previous speculations, the authors did not observe evidence that surface steps are preferential nucleation sites.
