Adsorbates

Caption

(a) When adsorbates bind to metal, they induce electric dipoles in the metal. Freely moving electrons in the metal can collide with these induced dipoles and lose their energy. (b+c) The efficiency of such a collision depends on the orientation of the induced dipoles and thus on the chemistry of the adsorbate.
