Crystal chemistry is one of the most important studies in materials science because various functional devices made of crystalline materials have been developed based on the knowledge of crystal chemistry. This course introduces the chemical principles behind crystals as well as description of structure-property relations in crystals, which forms the basis of crystal chemistry. Topics also include X-ray structure determination which is how to know crystal structures of representative inorganic materials. The former half of the lecture focuses fundamental of X-ray diffraction and their use in structure determination in inorganic crystals. The letter half of the lecture is for relationship between crystal structure and physical properties on inorganic crystals will be explained.
The purpose of this lecture is to understand technique and its mechanism of structure determination of inorganic crystals as well as relationship between crystal structure and physical properties on inorganic materials. Furthermore, this lecture aims to give the students the ability to design functional inorganic materials and think the application, through the learning of the relationship.
