Class Objectives /Class Outline	Course Theme and Learning Objectives   In dielectric research, structural properties have traditionally been discussed primarily in terms of lattice systems. Therefore, many physical properties could be explained by understanding static structures such as atomic arrangements and crystal symmetry, as well as structural changes associated with phase transitions.   In this course, after acquiring fundamental knowledge necessary for structural studies of dielectrics—including crystallography, diffraction physics, and phase transition theory—students will also learn about local structures, structural fluctuations, and lattice vibrations, whose importance has increased in recent years, and their relationships to physical properties.   In particular, in addition to average structure analysis using X-ray and neutron diffraction, this course aims to provide a multifaceted understanding of the structural properties and phase transitions of dielectric and ferroelectric materials through the study of dynamic structures using light-scattering techniques such as Raman spectroscopy. Although the course focuses on dielectrics, the concepts and methodologies introduced are widely applicable to structural studies of solid-state materials in general. The goal is for students to become capable of applying these approaches to their own research. Course Overview   The course begins with an overview of structural property research, followed by fundamental topics in crystallography and diffraction physics. In crystallography, lectures will focus on point groups and space groups, emphasizing their relationship to structural properties. In diffraction physics, students will learn about crystal structure analysis and electron density analysis using X-ray diffraction and neutron scattering.   In the latter half of the course, topics will include local structure analysis using diffuse scattering and the study of lattice vibrations and structural fluctuations using Raman spectroscopy, in order to understand the phase transitions and structural properties of dielectric and ferroelectric materials.   There will be no written examination. Instead, students will be evaluated through report assignments designed to assess their understanding and ability to apply concepts in crystallography, diffraction, and light scattering.
