Abstract:
The effect of an induced deformation and the influence of a planar electric field on the ground state of the ferroelectric Ba$_{0.7}$Sr$_{0.3}$O$_{3}$ thin films deposited on (001)-oriented cubic substrates have been investigated. The dependence of the pyroelectric coefficient on the electric field strength $E_x$ in the film plane has been constructed for the values of the induced strain that correspond to different ground states of the film. In the regions where the film can operate in the mode of a dielectric bolometer, there is an electric field in which the pyroelectric coefficient reaches the extreme value. There is also a value of the induced strain at which the pyroelectric effect is most pronounced.
