Syllabus

Course overview and goals

A solid composed of Avogadro's number of atoms exhibits an electronic state that reflects the periodicity of its crystal lattice. In this lecture, students can understand the formation of bands by LCAO approximations and electronic structures of typical inorganic solids starting from the molecular orbital method, which is familiar to students in chemistry field.

Course description and aims

Students can understand the periodicity of crystal lattices based on wave vectors and explain the dispersion relationship between wave vectors and energy. In addition, students can explain electronic structures of solids based on their crystal structures, constituent elements, and valence.

Keywords

Molecular orbital, Bloch's theorem, Free electron model, LCAO approximation, Crystal-field splitting

Competencies

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

Class flow

The class will be conducted in the form of a combination of slides distributed in advance and written materials on the board. The lectures will be given on the assumption that the students have thoroughly prepared for the lectures. A 15-minute quiz will be given at the end of each lecture.

Course schedule/Objectives

	Course schedule	Objectives
Class 1	Bloch's theorem	Students can derive Bloch's theorem from a one-dimensional atomic chain.
Class 2	One-dimensional band structures based on linear combination of atomic orbitals method	Students can draw band structures of simple one-dimensional atomic chain using the LCAO approximation.
Class 3	Nearly free electron model	Students can explain the behavior of free electrons in a very weak periodic potential.
Class 4	Relaxation time approximation and electronic conduction	Students can understand the scattering of conduction carriers using relaxation time approximation and explain electrical conduction in metals.
Class 5	Two-dimensional band structures based on nearly free electron model and tight-binding approximations	Students can draw band structures of two-dimensional lattices based on the nearly free electron model and tight-binding approximation.
Class 6	Band structures in real solids	Students can explain band structures of typical solids.
Class 7	Exercises and explanations	Students can increase their understanding of lecture contents through exercises and self-evaluate their level of achievement.

Study advice (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.
