The Structure of Small Gold Crystals
The structure of small gold crystals with diameters between 2 and 6 mm generated by the inert gas evaporation technique (GET) has been investigated by high resolution electron microscopy. The structures observed range from a single crystal (about 56%) to singly or doubly twinned particles and multiply twinned particles containing partial dislocations. The tendency to form perfect single crystals increased with decreasing size. The size-dependence of the microstructure observed may be caused by particle collision and controlled by the energy of the grain boundaries formed between colliding crystals.
