The primary objective of this course is to enable students to understand and systematically organize three seemingly distinct
physical phenomena—ion conduction, superconductivity, and semiconductors—based on a common fundamental concept:
the behavior of carriers (electrons and ions) in solids.
Rather than starting from specific materials or device applications, this course begins with fundamental concepts of solid-state physics, such as energy levels, electronic states, and the wave nature of particles.
Students will then learn how these concepts manifest in ion conduction, superconductivity, and semiconductors, and how they give rise to different physical properties in each field.
Through this course, students are expected to develop the ability to analyze materials and physical phenomena based on conceptual understanding, rather than relying on memorization of formulas or isolated examples.

Through this course, students are expected to develop the ability to analyze materials and physical phenomena based on conceptual understanding, rather than relying on memorization of formulas or isolated examples.
This course covers three major classes of physical phenomena that play essential roles in energy materials:
ion conduction, superconductivity, and semiconductors.
Each topic is discussed from a unified perspective—namely, the behavior of carriers (electrons and ions) in solids.
Instead of listing materials or applications independently, the course emphasizes fundamental solid-state concepts such as band structure, electronic states, and the wave nature of particles, and examines how these concepts connect the three fields.

- Explain the motion of electrons and ions in solids from the viewpoints of energy levels, electronic states, and wave properties.
- Understand that ion conduction, superconductivity, and semiconductors, while different phenomena, can be described within a common physical framework.
- Analyze the behavior of materials and devices based on physical intuition and conceptual understanding rather than rote memorization of formulas.

This course consists of the following topics:
Carrier (ion) transport mechanisms and materials design in ion-conducting solids
Fundamentals of superconductivity (zero resistance, perfect diamagnetism, BCS theory) and high-temperature superconducting materials
Band structure, electronic states, PN junctions, and transistor physics in semiconductors
Organization of the common concept of “carriers in solids” across the three fields
Lectures involve explanations based on solid-state physics and mathematics (including differentiation, integration, and functions).
While emphasis is placed on physical meaning rather than mathematical derivations themselves, these elements cannot be avoided in achieving a proper understanding of the subject matter.
Online and In-Person Participation
This course supports online participation.
However, the course places strong emphasis on:
Real-time supplementary explanations using figures
Additional explanations through blackboard work and oral commentary
Adjustment of explanations in response to students’ reactions
As a result, there may be differences in the amount of information and learning experience obtained by in-person participants and online participants.
While online participation allows students to grasp the overall structure of the lectures, it should be understood in advance that the same level of educational effectiveness (100%) as in-person participation cannot be guaranteed.

Final report: 100%
In evaluating the report, priority is given not to the correctness of equations, but to whether students have thought through the lecture content and articulated their understanding in their own words.
A score of 60 points or higher is required to pass the course.
