X-ray diffraction and electron diffraction are extremely effective methods for conducting structural analysis of crystalline materials. In this course students study kinematic theory and dynamical theory, and learn through exercises the principles and specific techniques of orientation analysis and structural analysis using X-ray diffraction.
By gaining an understanding of the special characteristics of X-ray and electron diffraction, students will learn to carry out material characterization with the most suitable technique.
At the end of this course, students will be able to:
1) Have and understanding of the principles of x-ray and electron diffraction.
2) Explain the differences between x-ray and electron diffraction.
3) Acquire the techniques and skills of materials characterization.

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
