The past decade has seen tremendous interest in design and “design research” in thin films, nano-ionics heterostructures and strain stabilization of fast conducting phases or defect densities at interfaces. The major driving force for these activities is that nanoscale materials and strained interfaces can offer novel electro-chemical functional properties, which lead to exceptional performance beyond classic extrinsic doping strategies that can be used in many technological fields such as solid oxide fuel cells, electrolysis, catalysis, membranes for gas separation, batteries and resistive random access memory. Therefore, the main objective of this symposium is to address the use of designed interfaces in strained thin films, heterostructures and low dimensional materials of ionic and mixed ionic conductors, with an emphasis on the required functionality such as ionic and electronic conductivity, enhanced reaction and transport kinetics, novel processing/integration strategies, thermochemical stability, and catalytic activity. In particular, understanding oxygen transport in hetero-interface materials, where interfacial strain can play a considerable role in tuning the oxygen migration barriers. Novel oxides heterostructure devices based on strain modulation, define new performances or operation schemes in this area and will also be part of this symposium.

Further, the research on two-dimensional semiconductors started with graphene, boron nitride, and molybdenum disulfide, whose unique electronic properties make them potential successors to silicon in future devices. However, a new class of 2D materials is still open to be explored, these are the 2D ionic materials in which this two dimensionality gives them special properties of their own.

The symposium will concentrate on a multidisciplinary approach of physics, chemistry, materials science, and engineering needed to advance this field. Experimental and theoretical progress made in the areas of structural/functional/chemical analysis and in issues related to synthesis approaches will be emphasized with their relation to practical technological applications.
