| Abstract | Molecular dynamics simulations of depositional growth processes of polycrystalline metal thin films have been carried out, in which an FS type embedded atom method (EAM) potential was used. With a preset fixed strain, a uniaxial internal compressive stress was introduced during the film growth, and the effect of internal stress on development of growth texture of thin films was simulated. The results show that internal stress does significantly affect the orientation preference of the grains in films. The stress-induced preferential development of the favored grain starts at the deposition surface and expands by consuming its neighboring grains. Under fixed compressive strain, the grains, of which the close packing direction orients away from the compressing axis, grow preferentially. The simulation has also revealed a critical feature in kinetics of such stress-induced texturing versus film thickness. Local twinning was found to occur in the shrinking grain, and the twin soon transferred to the structure of the expanding grain. After the expansion completed, a mismatch dislocation may be left at where the shrinking grain disappears. |
