Abstract

By performing scaling experiments [1] and examining the evolution of the spatial second moment of the concentration profile, it was shown that the diffusion coefficient of gold in amorphous silicon is both concentration and time dependent. The second moment curves for different temperature anneals can be scaled to a master curve using a factor with an activation enthalpy of 2.0 eV.
