• We report a quantitative study of the energetics in one- to two-dimensional structure transformation of 3-atom Ir atomic clusters on Ir surfaces. On the (111) plane, the temperature dependence of the ratio of the probabilities of observing a 1-D and a 2-D structure exhibits a simple linear Arrhenius behavior. The 2-D structure is more stable and the difference in the cluster binding energies is 0.098±0.004 eV. In contrast, on the (001) plane, the 1-D structure is more stable, and the energy difference is 0.335±0.015 eV. In addition, a significant deviation from the simple linear Arrhenius behavior is found at low temperatures.
