Abstract

We have generated two-dimensional grain structures by considering constant growth of regions which nucleate under various conditions. We have considered continuous nucleation at a constant rate, nucleation site saturation, continuous nucleation with nucleation-exclusion zones surrounding the growing regions, and decaying nucleation rates. The microstructures resulting from these varying conditions differ markedly in their topological and geometric properties.

We have also developed a program which models grain boundary motion in structures resulting from nucleation and growth. Results from these models will be compared to observed microstructures in thin metallic and semiconductor films and should provide insight into the mechanisms of microstructural evolution and control.
