Characterization of materials is essential to the systematic development of new materials and understanding how they behave in practical applications. This course focuses on the principal methods required to characterize broad range of materials such as metal, alloys, semiconductors, insulators, polymers, ceramics, nanostructures etc. for their applications based on mechanical, electrical, optical, magnetic, thermal properties of materials.


The topics covers structure analysis tools, microscopy techniques, thermal analysis technique, electrical characterization, magnetic characterization, and optical spectroscopy, and other techniques for characterization of nanophase materials. The aim of this course is to provide introductory understanding of number important techniques in terms of the instrumentation, working principles, and information obtained and possible analysis of the materials.


This course is targeted towards undergraduate and postgraduate students of physics, materials science, metallurgy, energy technology, electrical engineering and electronics, polymer science and engineering etc.
