Crystals and crystal structures 1. Bravais lattices2. Miller indices, crystal planes and directions3. Common semiconductor crystal structures4. Growth of semiconductor crystals Solid materials are classified by the way the atoms are arranged within the solid. Materials in which atoms are placed at random are called amorphous. Materials in which atoms are placed in a highly ordered structure are called crystalline. Poly-crystalline materials are materials with a high degree of short-range order and no long-range order. These materials consist of small crystalline regions with random orientation called grains, separated by grain b
