Course Learning Outcomes
This course will provide basic learning of semiconductors to students. They will have concept of band gap, excess charge carriers, fermi level,optical absorption and direct and indirect recombination of charge carriers. Learning of all these concepts will be beneficial in their research work of MS and then PhD.
