Project H – Stress Modulated Electromechanical Coupling of Lead-Free Ferroelectrics
Photoferroelectrics possess both ferroelectricity as well as light sensitivity, which is interesting for multisource energy harvesting. Despite their potential importance, there remain a number of open questions that will be addressed in this project. Therefore, the aim of this project is to experimentally investigate the influence of stress on photoferroelectrics. Here, compositional band gap tuning will be accomplished through data driven automated powder dosing system to carefully control the composition over a widely material range. Following this, a combination of macroscopic and stress-dependent diffraction, microscopy, and spectroscopy techniques will be employed to experimentally characterize the influence of mechanical stress. Here, collaboration with our partners at the Nagoya Institute of Technology will be important.
