Abstract
Reconstruction of the Cu(001) surface due to oxygen gas impingement on a clean copper surface was directly observed by in situ UHV-TEM. Stra in contrast between differently oriented surface reconstruction domain s, assumed to be root 2 x 2 root 2 R45, were clearly visible by this m ethod. The reconstruction precedes the nucleation of Cu2O islands. Whe n Cu2O islands were partially reduced and then re-oxidized, a dwell ti me before formation of Cu2O was noted, demonstrating that a reconstruc ted Cu-O surface monolayer is necessary before oxide formation.
