Atomic relaxations on Cu(100) and stepped Cu(410) and (510) surfaces were measured using a few hundred keV He+ ions in channeling and double alignment geometries. On stepped surfaces, we have also attempted to determine the specific relaxation of edg

A theoretical description of the exchange of impurity atoms between the surface and the bulk is presented, with the assumption that desorption can be neglected. The analysis shows that the segregation isotherm — i.e. the relationship between surfac

Ag Mo and Cu Mo interfaces are created by evaporating a silver (or copper) thin film onto a (110) molybdenum single crystal. Growth takes place according to epitaxial relations and the interface is expected to be as coherent and clean as possible. Bo

The interaction between monoatomic steps on a vicinal ∼ (111) copper surface and the adsorbed sulphur monolayer has been investigated by a method involving the existence of two possible structures of the monolayer. The parts of the surface occupied

Vicinal surfaces of copper and gallium arsenide samples are examined with LEED and RHEED techniques. The assessments obtained by the two techniques are compared and a significant advantage of RHEED is demonstrated.

All vicinal surfaces 4° off the copper densest planes, (100) and (111), clean and under O, S and Pb adsorption, are investigated by LEED techniques. On such surfaces, the mean terrace width is constant — and large — and the mean step direction t

We describe an apparatus for performing LEED experiments down to 10 K and with possible temperatures variations as fast as 100 K/min in the range 10–300 K. We discuss the results obtained in the two typical cases: first on Si (111) 7×7 (clean surf

On présente un appareillage permettant l'étude par diffraction d'électrons lents (DEL) de surface refroidis à des températures aussi basses que 20 °K et ajustables rapidement dans la gamme 20 °K-150 °K. On met en évidence les difficultés pr

Leed reveals the interaction between an electron beam and the first atomic layers of a crystal; it should therefore give information about surface atomic vibration modes. The present note concerns an interpretation of data for Si (111) using dynamic

Previous work carried out in this laboratory, in the field of reversible chemisorption, has been concerned with the thermodynamics of the systems copper—sulphur and silver-sulphur. We have measured in particular, the maximum quantities of sulphur a
