Abstract
A thin stearic acid layer consisting of microcrystalline grains a few micrometres in diameter was formed by vacuum evaporation onto a metal-coated glass substrate at room temperature. The layer was maintained at a controlled temperature and then melted by laser beam irradiation at a wavelength of 633 nm; the melted grains recrystallized to give larger planar crystallites. The effects of laser annealing were influenced by impurities in the stearic acid, the type of substrate, the scanning conditions and the substrate temperature. When a metal-coated substrate with “grooves” was used, the size of the recrystallized stearic acid crystallites was larger than for a plane substrate.
