Abstract
The effect of the synthesis temperature on the microstructure and the electrophysical properties of metal–dielectric–semiconductor structures based on ferroelectric films of the composition Ba0.8Sr0.2TiO3 upon the formation of p-type silicon substrates with [100] orientation is studied. It was experimentally established that an increase in the synthesis temperature leads to an improvement in the dielectric and piezoelectric properties of ferroelectric films. The temperature stability and stability in the behavior of the capacitance–voltage characteristics of MIS structures on the number of switching cycles are shown.
