Electron holography of metal-embedded ferroelectric nanoparticles

Nanoparticles (NPs) made of materials that are ferroelectric in bulk form (e.g. BaTiO) lose their polarization. To prevent the disappearance of ferroelectricity, depolarization fields need to be compensated. An option for doing so, is to embed the NPs in a metallic matrix providing the necessary energy relief. This project consists of electron holography experiments carried out on a reference sample of BaTiO NPs deposited on a substrate, compared with a sample of BaTiO NPs embedded in a metal matrix, with the goal of demonstrating the preservation of ferroelectricity in the embedded sample
