The growth, structure, morphology, and composition of Fe films deposited on CoGa(100) at 550K was studied by thermal energy helium atom scattering (TEAS), Auger electron spectroscopy (AES), and low-energy electron diffraction (LEED). The misfit betwe

The thermal stability of very thin Co(0.9 nm≈7 ML)/Fe2O3(1 nm) double layers, deposited on Cu(110), was studied by Auger electron spectroscopy, thermal energy helium atom scattering, and low energy electron diffraction. Ordering of the double layer

The oxidation of a CoGa(100) surface at high temperatures has been studied by scanning tunnelling microscopy (STM) and auger electron spectroscopy (AES). When CoGa(100) is oxidised at a sufficiently high temperature (>600 K), an ordered Ga2O3 film is

The oxidation of the CoGa(1 0 0) surface at temperatures above 600 K has been studied by means of thermal energy helium atom scattering and Auger electron spectroscopy. The oxide grows in large domains with an estimated mean size of 40 nm or larger,

We have grown an ultra-thin film of iron oxide by oxidising a smooth epitaxial 5 ML Fe film which was deposited on Cu(1 1 0). In order to prevent roughening of the Fe film, the oxidation of the iron took place at 130 K. At low oxygen exposures, 950 K

The preparation of an ordered Ga 2 O 3 oxide on the CoGa(1 0 0) surface by exposing the surface to oxygen at room temperature and subsequent annealing has been studied by thermal energy helium atom scattering and Auger electron spectroscopy. During r

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

The diffusion of vacancy islands on Cu(111) and Ag(111) and of adatom islands on Ag(111) has been studied using fast scanning STM. Diffusion of atoms along island edges (periphery diffusion) is much more effective in contributing to the diffusion of

The absolute measurement of free energies associated with crystal steps on a metal surface has been a long-standing problem. We report a reliable estimate of the step free energy on a Cu(111) crystal surface, based on an analysis of island shape fluc

The reaction between hydrogen and oxygen on Pt(111) is investigated with molecular beam relaxation spectroscopy in the temperature range between 300 and 1200 K. Three procedures were used for preparing the surface, resulting in different reactivities
