Occupation of adsorption sites controlled by phonon entropy

Occupation of adsorption sites controlled by phonon entropy

Cobalt adsorbed on Ni(100) displays a reversible change in the occupation of bridge and top sites with temperature. The equilibrium is controlled by the contribution of the hindered translation modes to the free energy.
