Ferroelectric domain structures of PbTiO₃ thin films with imprinted ferroelectric hysteresis loops.

ABSTRACT: Understanding and controlling the domain structures and their stability in ferroelectric thin films is crucial for advancing technologies such as energy storage, memory devices, and sensors. By optimizing domain behavior, it is possible to enhance the performance, efficiency, and reliability of ferroelectric-based systems in these applications. Here, we investigated the imprinted ferroelectric hysteresis loops and the imprinted ferroelectric domain structures of the PbTiO₃ (PTO) multilayer thin films, including the oxygen depletion layer. The PTO multilayer thin films were made of a structure of DPTO/PTO/Pt/glass by PTO and PbTiO_3-δ (DPTO) layers by pulsed laser deposition. When the thickness of the DPTO layer was increased to 0, 5, and 7.5 nm, it was observed that th
