he diffusion mechanism of the Ni in amorphous Si was studied by in situ X-ray diffraction technique in amorphous Ni/Si multilayer. The temperature dependent diffusivity of Ni in amorphous Si was obtained in the form of Arrheneius relationship. A trap-retarded interstitial diffusion mechanism is suggested to explain the diffusion process of Ni in amorphous Si.
