Mechanical strain-enhanced ionic-conductivity in metal oxide membranes for energy applications
Elastic strain generated at the heterointerface between different metal oxides (in oxide nanocompo-sites) have been proposed as a strategy to intrinsically enhance the ionic conductivity at low opera-tion temperatures. Typical strain achieved by selected lattice mismatch at the heterointerface, can be only as high as about 2 − 3%. We investigate an alternative methods for straining oxide-ion conductor thin films and membranes at much higher levels toward plastic regime in order to enhance their ionic conductivity far beyond the current limits. To this end, single- and poly-crystalline thin films of typical oxide-ion conductor materials, will be prepared and transferred into bending setup to incrementally impose strain levels.
