Class Objectives
/Class Outline 〇 Course Theme and Learning Objectives
Research on dielectric materials has traditionally focused primarily on crystal lattices and their structure–property relationships. Consequently, many physical properties can be understood by considering static structures, such as atomic arrangements and crystal symmetry, as well as the mechanisms of phase transitions.
   In this course, students will acquire fundamental knowledge required for research on the structural physics of dielectric materials, including crystallography, diffraction physics, and phase-transition theory. They will also study research examples in which the microscopic origins of dielectric properties have been investigated using electron-density analysis and Raman scattering.
   In particular, the course aims to provide a multifaceted understanding of the structural properties and phase transitions of dielectric and ferroelectric materials. This will be achieved through the analysis of average structures using X-ray and neutron diffraction, together with the investigation of dynamic structures using light-scattering techniques, particularly Raman spectroscopy.
   Although the course focuses on dielectric materials, the concepts and methods covered are broadly applicable to structural studies of solid-state materials. By the end of the course, students are expected to be able to apply these concepts and techniques to their own research.

〇 Course Overview
The course begins with an introduction to research on the structural physics of materials, followed by the fundamentals of crystallography and diffraction physics.
   The crystallography section focuses on point groups and space groups, with particular attention to their relationships with the structural properties of materials. The diffraction physics section covers crystal structure analysis and electron-density analysis using X-ray diffraction and neutron scattering.
   In the latter half of the course, students will study lattice vibrations and structural fluctuations using Raman spectroscopy in order to understand the phase transitions and structural properties of dielectric and ferroelectric materials.
