Surface disordering of Ag(1 1 0) studied by a new high resolution scattering apparatus

The main features of a new experimental setup devoted to the study of the structural and dynamical surface properties are discussed. The apparatus combines the thermal energy He atom- and the low energy ion-scattering techniques with time-of-flight detection of the scattered fraction. The performances of both techniques are tested exploiting them to characterize the evolution of surface disorder on Ag(1 1 0) near the onset of the roughening transition at ∼600 K. Information on self-diffusion in the temperature range up to 775 K is provided.
