Solid state ionics: advanced functional materials for solid state devices

Defects, surfaces and interfaces play a major role in the transport and catalytic properties of functional materials. This symposium will focus on strategies to understand and control the functional properties of ionic and mixed conducting materials, with a view toward their application in solid state devices, such as batteries, solid oxide cells, gas sensors and memristive devices.

Scope:

The functional properties of solid state ionic devices, such as batteries, solid oxide cells (SOCs), gas sensors and memristive devices, strongly depend on mass and charge transport occurring in the nanoscale. These processes are related not only to the bulk material itself and the surrounding conditions, such as temperature, oxygen partial pressure or applied electrical field, but also on the presence of local heterogeneities, mainly point defects, grain boundaries, surfaces, disolcations and interfaces. It is increasingly common for researchers to seek novel and optimized functionalities in advanced materials through the creation of “natural” or artificial interfaces (e.g. bilayers, multilayers), controlled grain boundaries (e.g. thin films with high densities of defects) and optimized surfaces (e.g. preventing segregation or enhancing surface kinetics).

The goal of this symposium is to move from the fundamentals – the physics and chemistry of defects in solid materials – to technological applications, thus linking theory, simulations, functional properties and real applications. This symposium will provide a forum for extensive discussion and exchange of information among researchers exploring defect management in functional oxides in different contexts and diverse applications. This will include state-of-the art methods for structural and chemical characterization such as high resolution transmission electron microscopy, synchrotron-based spectroscopy and diffractometry, scanning probe microscopy and atom probe tomography, combined in many cases with modeling and simulation methodologies such as density functional theory and molecular dynamics. In addition, new methodologies for engineering ionic transport in functional materials will also be one of the main topics under discussion, with special emphasis in high throughput screening, heterostructuring, doping and strain. Electrolysis, switching phenomena, photocatalysis, gas sensing, and thin film based solid state devices for energy and informatics (batteries, solid oxide fuel cells, memristors) will be some of the main applications and devices to be discussed.
