Learning Outcomes

Material & device characterization techniques [2013]

  • To provide the basics of each technique including instrumentation, samples preparation and the applicability of these techniques.

  • Develop the concepts on the several materials characterization techniques at the morphological, structural and chemical level.

  • Demonstrate knowledge about the characterization methods based on microscopy, microanalysis and diffraction techniques, and surface and spectroscopy analysis.

  • Finally, develop the acquisition skills in the use and selection of advanced experimental techniques for characterization of materials and application of these techniques to solving problems in materials science and engineering.
