Course description and aims

To understand the origin of solid state physics, crystal and phonon are essential. The concept of crystal structure based on symmetry can easily explain the solid state composed a lot of atoms. To acquire the quantized phonon from the wave of lattice vibration comes from ordered arrangement of atomic coordination in crystals, students can contribute to develop a variety of materials support our society. From an idea of solid, students can grasp structures on atomic or molecular scale, and reach the comprehensive solid state physics.

Student learning outcomes

At the end of this course, students will be able to understand and explain the solid state physics of lattice vibration and its quantization based on the common concept of geometric crystallography and symmetry of crystals. And also, students will apply the fundamental knowledge of atomic coordinationand lattice vibration in crystals to predict material properties.
This course focuses on symmetry, point group and space group determined crystal structures, and covers fundamental knowledge of solid state physics such as wave of lattice vibration, Brilluouin zone, phonon, specific heat, heat conductivity.
