The nucleation and growth of the condensate clusters during the early stages of the vapour deposition process were studied by depositing silver vapour on silicon, glass, mica, NaCl and KBr in a small coater. It was observed that the formation of the condensate film can be divided into four stages and the condensate clusters exhibit liquid-like behaviour during their early stage of growth. The mode of cluster growth is affected by the interfacial properties between the condensate and the substrate. The effect of surface roughness on the cluster growth is relatively insignificant and the experimental reproducibility is usually poor because of unavoidable contamination.
