Abstract:
The growth of Fe–Ni based amorphous nanocolumns has been studied using atomic force
microscopy. The root mean square roughness of the film surface increased with the deposition time
but showed a little change at higher deposition time. It was found that the separation between the
nanostructures increased sharply during the initial stages of growth and the change was less
pronounced at higher deposition time. During the initial stages of the column growth, a roughening
process due to self shadowing is dominant and, as the deposition time increases, a smoothening
mechanism takes place due to the surface diffusion of adatoms
