Symposium

F05: Interfaces in functional materials: Structure, properties, anisotropy and modelling

Belongs to:
TopicF: Functional Materials, Surfaces, and Devices

The structure of interfaces plays a key role in processing and performance of crystalline functional materials, such as sensors, ferroelectric actuators, dielectrics and ionic conductors. However, not only the properties of materials depend on interfaces, but the formation of a microstructure as well, i.e. sintering and grain growth. Possible impact on microstructure and its evolution arise due to the boundary structure, local defect redistribution, segregation, space charge, mechanical stresses and the anisotropy of transport processes at interfaces. These effects and their interplay with the materials properties need to be understood on a fundamental level to tailor a material for a given application.

This symposium covers basic and applied science topics on all aspects of interfaces, microstructure evolution, thermodynamics and their relationship to the materials properties, using experiments as well as simulations. The overall focus is on functional ceramics, but other crystalline materials are considered as well.

Proposed session topics

Interface structure and anisotropy

  • Atomic structure, segregation and stoichiometry
  • Grain boundary transitions
  • Mechanisms of interface motion

Interface properties

  • Defects and space charge

  • Mechanical properties

Sintering and grain growth

  • Conventional sintering and field assisted sintering
  • Grain growth and abnormal grain growth
  • Effects of non-stoichiometry
  • Simulation of microstructural evolution
  • Anisotropy of interfacial energy and motion.
