报告题目:Chemical Bonding Analysis in Intermetallic Compounds: A Position-Space Approach
报告内容简介:
Chemical bonding being a system of physical forces within a chemical entity create a natural bridge between chemical and physical behaviors of materials. Quantum chemical bonding indicators in real space help to find electronic counts necessary to stabilize structural pattern with a band structure with a (pseudo)gap and a strong DOS gradient at the Fermi level [1], and at the same time to understand the reasons for appearance of special features in the real structure. As an example, spatial distribution of regions with di?erent types of chemical bonding – bonding inhomogeneity and anisotropy - in?uences especially the thermal transport more than other crystallographic only features in thermoelectrics [2].
