We have grown an ultra-thin film of iron oxide by oxidising a smooth epitaxial 5 ML Fe film which was deposited on Cu(110). In order to prevent roughening of the Fe film, the oxidation of the iron took place at 130 K. At low oxygen exposures, <2x10 -6 mbars, a surface oxide forms. After completion of the surface oxide layer a disordered Fe 2 O 3 film grows. Upon annealing,...
The room temperature growth of Fe on the Cu(110) surface was studied with helium scattering, Auger electron spectroscopy and low energy electron diffraction. On the Cu(110) surface, iron grows in the form of three-dimensional islands. Segregation and intermixing are observed at temperatures above 490K. Though these processes are observed in about the same temperature range, we did observe a much smaller...
