The Structure of Crystalline Solids

The Structure of Crystalline Solids. Atomic Arrangement. Crystal structures have short-range order and long-range order (on a lattice - see CDROM) unit cell = smallest grouping of atoms that show the geometry of the structure and be repeated to form the structure

Linear and Planar Atomic Densities

Linear and Planar Atomic Densities. Linear Density: Directional equivalency is related to the atomic linear density in the sense that equivalent directions have identical linear densities. The direction vector is positioned so as to pass through atom centers.

Single Crystal

Single Crystal. A garnet single crystal found in Tongbei, Fujian Province, China. If the extremities of a single crystal are permitted to grow without any external constraint, the crystal will assume its geometric shape, with flat surfaces as shown in the figure.
