Purpose of class
Condensed matter physics explores the microscopic origins of material properties through the behavior of electrons and atoms. While controlling composition and structure is vital in materials engineering, true design requires understanding the underlying logic of functions, such as electrical conductivity. This course connects abstract concepts of quantum and statistical mechanics with real-world battery phenomena. By using rechargeable batteries as a practical scaffold, students will build a theoretical foundation linking mathematical equations to actual material properties, including crystal structures, ion diffusion, and phase transitions.
Course description
This course examines the origins of material properties through four stages: atomic arrangement, thermal behavior, electronic states, and functional expression. We first explore crystal structures and reciprocal lattices to understand how lattice vibrations and diffusion affect transport properties. Next, we introduce the fundamentals of quantum mechanics to develop metal electron theory and band theory. Finally, advanced topics such as magnetism and strongly correlated systems are discussed using transition metal oxides as primary examples.
Goals and objectives
  1. Understand the relationship between crystal structures and reciprocal space to physically explain dynamic changes in atomic arrangements from measurement data like XRD.
  2. Master the concepts of lattice vibrations (phonons) and defects to formulate mechanisms for thermal conduction and ion diffusion.
  3. Apply quantum electron theory to describe the classification of metals, semiconductors, and insulators, as well as interface phenomena from an energy-level perspective.
  4. Logically analyze how microscopic interactions and thermodynamic stability contribute to macroscopic properties such as magnetism, dielectricity, and phase transitions.
