We have investigated atomic diffusion properties near the amorphous/crystalline (formula presented) Si(001) interface during solid-phase epitaxy (SPE) of Si based on molecular-dynamics simulations using the Tersoff potential. It has been found that the mean-square displacement of the Si atoms in an amorphous layer with a thickness of 10 Å at the (formula presented) interface is larger than that in bulk amorphous Si. This can be attributed to local heating due to crystallization of amorphous Si during SPE growth.
