چکیده انگلیسی
The surface of Cu(111) was exposed to molybdenum hexacarbonyl Mo(CO)6 with monolayer coverage at temperature 160Â K and studied by a Scanning Tunneling Microscope. The monolayer structure has a hexagonal arrangement and forms a (â7Â ÃÂ â7) R19 superlattice on the copper (111) plane. Upon repeated scanning the monolayer is transformed into a (1Â ÃÂ 2) superstructure with 3-fold oriented domains. The domains of (1Â ÃÂ 2) superstructure can change orientation under scanning according to 3-fold surface symmetry. From analysis of the domain mobility, it follows that CO groups of carbonyl fragments are organized in the (1Â ÃÂ 2) superstructure conditioning the domain reorientation. The observed structure transformation under scanning is a result of stimulated dissociation of molybdenum hexacarbonyl on the copper surface.
