PHYS 331 (2-0-2) Introduction to Physical Properties of Solids
General considerations of solidification of aggregates of atoms to form the solid state. The structure of ideal crystalline solids: the unit cell, the different types of crystal structures, i.e. simple body centered and face centered cubic, diamond cubic, and the hexagonal close packed structures. Anisotropy, textures and preferred orientations. Miller indices, crystal directions. Stereographic projections. Diffraction and methods of materials characterization: X-ray diffraction methods, X-ray fluorescence methods. Binding in solids: the internal energy of a crystal, ionic binding, Van der Waals solids, covalent binding and metallic binding. Molecular solids. Models to explain the properties of solids: the free electron theory, the zone theory. Applications to zone theory to explain: thermal properties of solids, electrical behaviour of conductors, semiconductors, and insulators. Alloy structures, magnetic properties, super-conductivity (a simplified approach). The mechanical properties and structure of real solids: Point defects in solids, dislocation types and interactions, grain boundaries, slip system solid solutions, preparation of single crystals, epitaxy and control of film properties.
