Course Description

There are various devices which make use of electrons and photons in solid state (or materials). The examples are solar cells, semiconductor lasers, and transistors. These devices are indispensable for all areas of technologies, and thus regarded as brains in society. In this lecture, we explain various phenomena based on electrons and photons in solid states, where the focus is on the interaction between solid states and photons via electron transitions.


Examination and submission of a few reports

Course Goals

Understanding of fundamental of band structures in solid state and the related phenomena such as light absorption and amplification based on the electron transitions between valence and conduction bands.

Course Topics

Theme Class number of times Description
Overview of solid-state electronics 1 After the explanation of progress in electronics based on solid-state electronics, we show the contents of this lecture.
Fundamentals of solid-state electronics 1〜2 First, we explain the method to derive band structure of solid state using Kronig-Penney model. Then, we describe various fundamental concepts in solid state, such as density of states, phonons, etc.
Photon absorption in solid state 4 We will explain the mechanism of photon absorption in solid state and derive some equations to expess the absorption quantitatively.
Amplification of light 2〜3 We will explain the mechanism of optical amplification and derive some quantitative equations.
Various photonic devices 3〜4 Various photonic devices based on the above discussions are given, such as solar cells, semiconductor lasers, etc.
Verification of understanding 1 We confirm whether the students can understand the above subjects.


Note stile
