S10 – Point Defects and Transport in Ceramics

This symposium highlights experimental and computational research aimed at understanding point defect equilibria and kinetics in ceramic materials. Defect chemistry governs conductivity in electronic, ionic and mixed-conducting ceramics, which are important for numerous applications including solid-state batteries, memristors, dielectrics, solid-oxide fuel cell, and sensors. Furthermore, defect transport is intimately related to microstructure evolution and many material degradation phenomena. We encourage symposium contributions that help establish a greater understanding of our ability to predict, design, and control defect equilibria to enhance ceramic properties and performance

Proposed Sessions

• Predictive point defect energetics and equilibria from density functional theory and other computational methods
• Structure and stability of defects and defect complexes via in-situ measurement (EPR, TSDC, EXAFS, etc.)
• Point defect segregation to dislocations, surfaces, grain boundaries, and interfaces
• Defect mobility and transport behavior
• Defect mediated properties (conductivity, grain growth, creep, magnetism, ferroelectric imprint, dielectric degradation)
