Outline and Purpose of the Course	Students will learn the basics of solid-state physics through turn-based lecturing and reading of chapters from Ch. 7 onward of C. Kittle's "Introduction to Solid State Physics." Specifically, the state of electrons inside crystals will be discussed based on Bloch's theorem, followed by understanding the band structure. Based on this, the course covers the electrical properties of semiconductors and concepts such as holes and effective mass. We will also discuss the Fermi surface of metals and understand their primary physical properties. In addition, we will learn experimental facts, phenomenological theories, and BCS theory on superconductivity.
Course Goals	Learning the basics of metal and semiconductor physics
Schedule and Contents	Lecture 1 Nearly Free Electron Model 　　Students will learn the Nearly Free Electron Model. Lecture 2 Bloch's Theorem 　　Students will learn Bloch's theorem and understand the energy gap that occurs using the Kronig-Penney model. Lectures 3-4 Energy Bands 　　The energy bands of crystals are considered using a two-wave approximation based on Bloch's theorem. Lectures 5-8 Semiconductors 　　Based on the energy band structure of semiconductors, students learn the concept of holes, and then study the concept of effective mass by considering the equations of motion that electrons and holes follow in semiconductors. Next, the carrier concentration is determined based on the statistical mechanics of electrons and holes in the semiconductor. In addition, students learn about mobility, conductions of impurity, thermoelectric effects, and motion of electrons in superlattices. Lectures 9-11 Metals 　　After learning that many of the electrical properties of metals are determined by the Fermi surface, students learn how to construct the Fermi surface for nearly free electrons. In addition, students learn how to calculate energy bands using tight-binding approximation, the Wigner-Seitz method, the pseudopotential method, etc. We also consider the quantization of electron orbits in magnetic fields and learn how to examine the Fermi surface by the de Haas-van Alphen effect. Lectures 12-14 Superconductivity 　　　Students learn the experimental facts of the phenomenon of superconducting, consider the theory of superconductivity, and study the London equation. Based on this, they discuss the London penetration depth and coherence length. In addition, we give a brief explanation of BCS theory and learn about the quantization of magnetic flux and the Josephson effect. Lecture 15 Feedback 　　Check the course's degree of achievement against the final goal. Review as needed.
Evaluation Methods and Policy	The evaluation will be conducted based on participation in discussions.
Course Requirements	Students should have an understanding of Chapters 1-6 of C. Kittel's "Introduction to Solid State Physics."
Study outside of Class (preparation and review)	Preparation and review are essential given the turn-based lecturing style of class.
