Abstract :
In this work we report the growth of high quality, fully epitaxial, mono-crystalline Pb (Zr0.5T0.5)O3 thin films with step flow growth mode by PLD. For the first time the study of self-polarization in doped mono-crystalline PZT thin films using PFM is presented. The direction of self-polarization in pure PZT on SRO is upwards whereas that of Fe dopes PZT is downwards. The behavior is explained by trapped oxygen vacancies at the film-electrode interface as well as lead vacancies gradient in the bulk.
