Singular Diffusion as a Function of Nanoparticles Size in Antimony Film–Selenium Particles and Antimony Film–Tellurium Particles

A recently developed chemical synthesis method using the nanoparticle size as a parameter has been applied to Sb film–Se particle and Sb film–Te particle systems. In the Sb–Se system, the diffusion of Se atoms to the Sb film can be clearly seen for Se particle sizes less than 50 nm. Diffusion of Sb atoms predominantly took place in the case of the Sb–Te system. The uniqueness of the reaction consists in the diffusion direction of nanoparticles. Comparison with previous work (Kaito et al., 1998b) is made on the basis of the particle stability and electronegativity.
