Preparation and

ReviewHandouts will be distributed, prior to class, and be described in detail with respect to preparation and review.

In the preparation, it is desirable to organize the questions.

Requirements In the lecture, we use Quantum mechanics, Statistical mechanics, Crystallography, Fourier transform, etc. So, your reviewing or self-education of the elementary knowledge about these subjects is recommended. Grading Method The criterion for evaluation is the level of understanding, and the evaluation is mainly based on the result of semester final examination. In addition, the reports and attendance of the lecture may also be taken into account. Practical Experience Summary of Practical Experience and Class Contents based on it Message Students, who will be involved in researches on solid state physics, material development and relevant work, are recommended to take this lecture. Other Please fill in the class improvement questionnaire which is carried out on all classes.

Instructors will reflect on your feedback and utilize the information for improving their teaching.
