Influence of the molar ratio Sr:Bi:Ta in bismuth-strontium tantalum films Sr<sub>y</sub>Bi<sub>2+x</sub>Ta<sub>2</sub>O<sub>9</sub> on structure and electrophysical properties
Polycrystalline thin films of bismuth-strontium tantalum SryBi2+xTa2O9 with different molar ratio Sr:Bi:Ta were obtained by sol-gel method. The formation of a phase with a perovskite structure has been established. Phase transitions have been confirmed by dielectric spectroscopy. In the mode of polarization switching spectroscopy, remnant piezoelectric hysteresis loops were obtained, which confirms the ferroelectric nature of the synthesized SryBi2+xTa2O9 films.
