Abstract
We propose a method for the calculation of the average size of spherical cl usters on a surface, using XPS emission intensity ratios. The method is app lied to the case of Cu clusters on Dow Cyclotene 3022. a low permittivity p olymer. It gives reasonable particle sizes and number densities, and shows that the clusters coalesce on annealing. TEM photomicrographs confirm the s ize and sphericity of the clusters formed.
