Course

Unit 1

Symmetry in Crystal Systems : Types of symmetry, plane, axis and centre of symmetry, crystal systems and symmetry elements. Law of rational indices, miller indices, Weiss indices – plane systems, space lattices, unitcells – unitcell dimension, determination. Space lattice – definition and types Bravais lattice – kinds of bravais lattices, number of atoms in SC, BCC, FCC lattices, void space, Radius ratio rule and application. Crystal defects – types of defects in crystals – stoichiometric defect – schottky and frenkel defects – Non-stoichiometric defects – metal excess and metal deficiency defects, influence of defects on the properties of solids.

Unit 2

Electrical and Magnetic Properties : Development of free electron theory to band theory of solids – metals and their properties; semiconductors – extrinsic and intrinsic, Hall effect; Insulators – dielectric, ferroelectric, pyroelectric and peizoelectric properties and the relationship between them. Dia, para, ferro, ferri, antiferro and antiferri magnetic types – selected magnetic materials such as spinels, garnets and perovskites, superconductors.

Diffraction Methods : X-ray diffraction – various methods of X-ray analysis of structure-ray diffraction pattern, X-ray scattering factor. Results and uses of Xray diffraction. Limitations of X-ray diffractions.
