Outline and Purpose of the Course  Students will learn the basics of solidstate physics through turnbased lecturing and reading of Chapters 26 of C. Kittle's "Introduction to Solid State Physics." Specifically, the diffraction of waves by crystals will be discussed, followed by the concept of inverse lattices. The course also covers the forces acting between the atoms constituting crystals, and discusses the elastic properties of crystals. Additionally, students will learn the properties of phonons that quantize the elastic oscillation of crystals and understand the thermal properties of crystals. Based on the free electron model, the electrical and thermal properties of metals will also be covered. 
Course Goals  Understanding the various underlying concepts in solidstate physics, such as inverse lattices, phonons, and free electrons 
Schedule and Contents  Lectures 12 Diffraction of Waves by Crystals Using Xrays as an example, students learn the basics of the phenomenon of diffraction of waves caused by crystals. Lectures 34 Reciprocal Lattice Vector Students learn to express conditions of diffraction using reciprocal lattice vectors and understand Ewald Construction. They will also learn about structural factors. Lectures 56 Crystal Bonds Students learn about the basic types of bonds that form crystals, i.e., van der Waals interaction, Ionic bonds, Metallic bonds, Covalent bonds, and Hydrogen bonds. Lecture 7 Elastic Constant of Crystals After learning the relationship between crystal symmetry and elastic constants, we study the behavior of elastic waves in cubic crystals. Lectures 89 Elastic Oscillation in Crystals Students learn vibrations of crystals with a monatomic basis and understand the concept of phonons. It is extended to the cases for crystals with two or more atoms per primitive basis. Lecture 10 Phonon Heat Capacity After studying the statistical mechanics of phonons, we introduce the Debye model for the density of states of phonons to estimate phonon contribution to the heat capacity. Lecture 11 Phonon Thermal Conductivity Students will study the thermal conduction by phonons and understand the contribution of the Umklapp process to the thermal resistivity of phonon gas. Lecture 12 Freeelectron Model of Metals Under the freeelectron model of metals, students learn the statistical mechanics of electron gases. Lecture 13 Heat Capacity of Electron Gases Based on the statistical mechanics of electron gas, we will discuss the heat capacity of electron gases. Lecture 14 Electrical and Thermal Conductivity of Electron Gas Students will learn the phenomenology of electrical and thermal conductivity of electron gases. In addition, we discuss the Hall effect. Lecture 15 Feedback Check the course's degree of achievement against the final goal. Review as needed. 
Grading Policy  The evaluation will be conducted based on participation in discussions. 
Prerequisites  Students should have a rudimentary understanding of quantum mechanics.
