### Course description and aims

This course focuses on the fundamentals of crystallography. We will start from the indexing of directions and planes in lattices, the crystal systems, and the Bravais lattice. This course also covers the principles and applications of stereographic projections and their application to the cubic system.

Through lectures and exercise problems, the course enables students to understand the basic concepts of crystallography.

### Student learning outcomes

At the end of this course, students will be able to:
1) Understand the concept of lattice and the general rules of lattice directions and planes.
2) Acquire the ability to handle stereographic projections of the cubic system.

### Keywords

lattice, crystal structure, crystal systems, Miller index, interplanar distance, coordination number, packing efficiency, zone, reciprocal lattice, stenographic projection, Wulff net

### Competencies that will be developed

 ✔ Specialist skills Intercultural skills Communication skills Critical thinking skills ✔ Practical and/or problem-solving skills

### Class flow

Attendance is taken in every class.
Towards the end of class, students are given exercise problems related to what is taught on that day to solve.

### Out-of-Class Study Time (Preparation and Review)

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.

### Textbook(s)

Course materials are provided during class.
