Annotation
Slow adatom diffusion on the periodic surface of the upper layer of a growing crystal that has not yet completely formed is considered. Island (cluster) motion is investigated as a factor that accelerates adatom diffusion and results in an entropy increase compared to the case of an already formed stationary substrate layer. The diffusion coefficient, entropy, and the effective temperatures that characterize these properties of the substrate have been introduced.
