Percolation scale effects upon amorphous structural phase transition in an alloy film

Abstract

Percolation structures are formed during the amorphous-to-crystalline phase transition induced by ion beam irradiation in Ni-Mo alloy films. It is found that the percolating networks emerged at the critical point of the transition and they were well fitted for the percolation scales. The direct observations, in this study, provide the evidences of the percolation behaviours upon such a phase transition in thin solid films.
