[Summary of the course] In this course, the electronic properties of solids will be explained in association with nature of the chemical bonding and crystallographically derived periodic potential. The topics include the electric conductivity and electronic structures of metals, semiconductors, insulators, superconductors, and quantum confined structures.
[Aim of the course] Based on the history that solid-state chemistry and solid-state physics have been complementarily developed, themes in each class are designed so that students understand close relations in the knowledges of solid-state chemistry and solid-state physics. In the beginning of each class, for example, explanations of a principle of chemistry are given, followed by a brief exposition of the related theory in the viewpoint of physics. Modern chemistry has been developed by discovery of a useful compound followed by synthesis and design of related compounds based on the knowledge of the physical properties. Meanwhile, new physical properties and functions are often found from among the codified group of compounds in a certain principle. From this point of view, this course encourages students to discuss and do exercises about problems.
At the end of this course, students will be able to:
1) explain the electronic properties of solids in association with nature of the chemical bonding and crystallographically derived periodic potential.
2) explain the principles that govern the electronic properties of solids based on molecular orbital theory, free-electron theory, and band theory.
Energy band, free-electron theory, density of state function, reciprocal lattice, systematic absences, x-ray diffraction, Hall effect, metal-insulator transition, Mott insulator, quantum well, high-Tc superconducting cuprate
