SYMPOSIUM FL | CIMTEC 2014

The evolution of the structure and properties of materials during processing and their degradation and working lifetime is often controlled by mass and charge transport processes. Further on, diffusion of electrons, spin-polarized carriers, ions, atoms, molecules or of more complex entities such as dislocation loops, grain boundaries, pores and gas bubbles either in crystalline solids or in less ordered or amorphous media may be critical for the feasibility and operation of a vast array of advanced applications, from, for example, high temperature structural components, to microelectronic, microionic, optical, superconducting and memresistive and switching devices.
Main objectives of this conference which follows the ones on the same subject held in the frames of CIMTEC Conferences are to update recent achievements in the fundamentals of transport mechanisms in inorganic materials and the role of transport in materials reactivity, synthesis, processing, properties, and device design and performance.
Covered are crystalline ionic/covalent materials, metals and metal alloys, intermetallic compounds, semiconductor materials, and amorphous solids, glasses and melts.
Special focus will be on transport phenomena in small confined systems and in nanostructures for their challenging relevance, as well as on novel theories and computational modeling and simulation approaches for defect formation, interaction, aggregation and diffusion, capable to direct or complement experiments.
Application engineering studies addressing the role of mass and charge transport as enablers for the design of new high performing devices, and/or the efficient operation of engineered components under service conditions of high temperature, thermo-mechanical stress and strain, corrosive environments, radiation, electrical and magnetic fields also will be suitable topics for discussion.
