Week 09-10(Lattice Vibrations)

Lesson Plan:

The student should have the following learning outcomes defined in terms of knowledge, skills and general competence:

  • Know the concept of phonons, and how the dispersion relationship appears for different lattice structures.
  • Explain how a lattice vibrates at finite temperature, and how these vibrations determine the heat capacity and conduction.
  • Know the concept density of states in one, two and three dimensions.
  • Explain simple theories for the conduction of heat and electrical current in metals.

Lesson Plan:

Lecture 01: Introduction to Lattice vibrations.

Lecture 02: Lattice vibrations in a 1D lattice.

Lecture 03:Lattice vibrations in a 3D lattice.

Lecture 04:Concept of Phonon in detail, its energy, and momentum.

Lecture 05: Phonon density of states.

Lecture 06: Dispersion relations.
