Abstract

Pulsed Laser Deposition (PLD) was used to deposit Pb(Zr,Ti)O3 thin films on high-grade steel Hastelloy. This material is suitable as substrate and electrode material as well. The deposited films were characterized with respect to their structural (XRD, RBS), topological (AFM) and their ferroelectric properties (P(E) hysteresis, retain and fatigue) which were found to be excellent. The ferroelectric properties in general, are sensitive to structural modifications and chemical doping and could therefore be influenced by ion implantation. Several species of ions (Ca+, O+) show different influence on the ferroelectric behavior and on the structural defects of the films. A subsequent annealing process can partially restore these modifications. The implanted Ca+ films were characterized by dielectric spectroscopy dependend on frequency and temperature to get information about ferroelectric domains.
