CHM 332: Principles of Solid State Chemistry and Crystallography (4)

Pre-requisites (Desirable): CHM 101, CHM 102 and CHM 301

Learning Objectives:

To learn the concepts related to the arrangement of atoms in solids and how these influence the properties of matter.

Course Contents:

  1. Concepts:  Structures  of  Ionic  Solids  (crystal  chemistry),  Metals  and  Alloys,  Band  Theory  in  Solids (Metals, Semiconductors, Inorganic Solids), crystal defects, non-stoichiometric  compounds, solid solutions, dislocations and stacking faults.
  2. Structure and Bonding in Solids: Factors governing formation of crystal structures, Kapustinskii's equation, Sanderson's Model, Mooser-Pearson plots, non-bonding electron effects.
  3. Phase Transitions: Buergers's (reconstructive and displacive), Ubbelohde's Classification (continuous and discontinuous), Applications of G-T diagrams, kinetics, critical size and nucleation rate, Martensitic, order­ disorder transitions.
  4. Structure Property Correlation in Materials: Optical, Dielectric and Superconducting properties.
  5. Symmetry in the Solid State: Unit Cell, Crystal Systems, Asymmetric Unit, Crystal lattices (2D), Bravais Lattices (3D), Miller planes (crystallographic directions and multiplicities) , d-spacing formula (resolution),Crystallographic Point and Space groups (equivalent points, Wyckoff positions, site occupancy factor).
  6. Elements of X-ray diffraction: Scattering by an Atom and Crystal, Bragg's Law, Reciprocal Lattice, Reflecting and Limiting sphere of reflection, systematically absent reflections.
  7. Crystal   structure determination: Structure Factor  and  Phase  Problem,   Electron   Density.  Maps, Anomalous  Scattering,  Thermal  Motion  Analysis , refinement  and  crystallographic  parameters  in  crystal structure  analysis,  dynamic  and  static  disorder,  the  physical  interpretation  of molecular  (Bond  lengths, angles and torsions) and crystal structures (Packing Diagram), Rietveld method in Powder diffraction.
