Solid State Physics-II

 (Theory)

 

 

 

The students will be able to:

  • get the knowledge about the Lattice Dynamics and Optical Properties of Solids.
  • apply the basics theory of conductors, semiconductors and get the idea of photoconductivity, photo-luminescence.
  • get an insight of different kind of defects in crystals like Point’s line, planar and bulk defects, colour centres, F-centre and aggregate centres in alkali halides.
  • compare different types of magnetism from diamagnetism to ferromagnetism and domain theory.
  • get the basic idea of the theory of superconductivity and their properties in the frame of BCS theory.

Approach in teaching:

Interactive Lectures, Discussion, Tutorials, Demonstration, Problem Solving in tutorials.

 

 

Learning activities for the students:
