To observe the singularity of clusters and ultrafine particles in low dimensions, a new experiment has been started on the Au-Cu system. The diffusion of atoms in the cluster and ultrafine particles has been observed including the direct observation at the interface. The alloy formation temperature decreases by about 50°C compared with the film - ultrafine particle. The diffusion rate difference observed in bulk phase is preserved in the alloy formation process.
