Investigation of the Effect of Crystallographic Anisotropy and Defects on the Electrocaloric Response of Stress-free Relaxor Ferroelectric Plates by Experimental and Analytical Techniques
Abstract
The research study that we propose on the investigation of the effect of crystallographic anisotropy and defects on the electrocaloric (EC) response of stress-free relaxor ferroelectric plates is in essence oriented towards developing a basic understanding of this phenomenon. However, its results may have relevance for aerospace applications, in addition to the obvious civilian applications. Due to their service environment, aerospace materials may face extreme conditions such as high temperatures, or high stress, electrical, magnetic, electromagnetic fields, particularly under reduced volume constraints. Electronic circuits and devices working in these extreme environments require compact, light-weight, efficient and environmentally friendly systems, materials for on-chip, or on-board micro-cooling. Additionally, energy storage applications may also require precise control of local temperatures in a large operational temperature range. Thus, increasing the electrocaloric effect (ECE) through the development and engineering of a crystallographic texture in relaxor ferroelectric materials in plate form may provide a viablefuture alternative.
