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.
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.
