Vapor-phase growth of amorphous materials: A molecular-dynamics study

We have studied the vapor-phase growth of a mixture of two differently sized Lennard-Jones particles as a function of relative atomic size and substrate temperature, and we investigated what influence the substrate has on the growth. As a function of relative atomic size there is an abrupt change from well-layered crystalline growth to a nonlayered disordered growth. This transition is not affected in a substantial way by temperature or size of the substrate atoms or by the periodic boundary conditions used in the calculations.
