This lecture will specfically cover Crystal Symmetries, Point Defects and Ionic and Electronic Transport. Besides, each seminar will provide importat crystal structure, Glide planes, Magnetic stmmetry,magnetic/color/back-white gropus;non crystallographic groups, Rogins and classification of point defects, Chemical equilibrium and Effect of doping impurities on defect equilibrium. The each content of seminar is posted below.
