Transport of adsorbates at metal surfaces: From thermal migration to hot precursors

Theoretical aspects and evolution of surface diffusion studies are discusse d with an emphasis on non-metallic adsorbates at metal surfaces. A survey o f the existing literature is presented with the main experimental results t abulated. (The tables and their updates are available online at http://ipen t.epfl.ch/gr_kern/jv_barth/SD_tables.html) Conception, theoretical and expe rimental work on transient mobility in the adsorption of gases on metal sur faces are summarized.
