Course Contents

Metals simple close packed structures, that are conventionally used to prepare powders at micrometer scale. Chemical Crystallography, External features of crystal, Crystal symmetry, Miller Indices, Point groups, Crystallographic terms. Laws of crystallography, Indexing of planes, X- ray diffraction Classification of crystals on the basis of crystal forces Bonding in solids: metals, insulators, conductors and semi conductors n- type and p-type semiconductors Basic simple structures such as salts (CsCl,NaCl, CaF2), oxides (Na2O) and sulphides (ZnS) and more complex structures: carbon-based structures (graphite and diamond) and oxides (rutile, perovskite, layered perovskite, spinel). The second part focussed on X-Ray diffraction techniques. First the basics of X-Ray diffraction is presented then the acquired knowledge is applied on the study of crystalline structures using X-Ray diffraction patterns obtained on powders. 3/ The last part deals with the description of Super conductors, Band theory of metallic state. Conductors semiconductors and insulators. Theories of superconductivity, Fermi level
