The illustration on the front cover refers to the article by Patrakov et al. on page 937 . The authors performed a density‐functional study on the mobility of cadmium and tellurium adsorbate atoms on reconstructed Te‐terminated (001) CdTe (2 × 1) surfaces. Potential energy surfaces for the motion of the adsorbate atoms reveal two potential energy minima for Cd as well as Te adsorption. The calculated potential energy barriers suggest that adsorption of a tellurium atom leads to adsorbates which may move along the surface (left 3D plot). On the other hand, cadmium adsorbate atoms are trapped in the global minimum (right 3D plot) as desorption is expected to be much more likely than motion along the surface.
