Abstract :
Electric properties of Au/PZT(65/35)/Pt MFM structures were investigated by measuring the D-E and C-V characteristics. Analysing experimental data, some important quantities were extracted (remnant polarisation; coercive field; acceptor concentration; Schottky barrier height). It was shown that in case of C-V measurements the PZT film behaves more like a semiconductor than a ferroelectric.
