  In this work the effect of amorphous substrate on crystallization is
addressed. By performing Monte-Carlo simulations of solid on solid models we
explore the effect of the disorder on crystal growth. The disorder is
introduced via local geometry of the lattice, where local connectivity and
transition rates are varied from site to site. A comparison to an ordered
lattice is accomplished and for both, ordered and disordered substrates, an
optimal growth temperature is observed. Moreover, we find that under specific
conditions the disordered substrate may have a beneficial effect on crystal
growth, i.e., better crystallization as a direct consequence of the presence of
disorder.
