Abstract

We studied the influence of the induced strain and applied electric field on the ground state of ferroelectric Ba0.7Sr0.3TiO3 thin films, deposited on the cubic (0 0 1) substrate. The dependence of the pyroelectric coefficient on the applied field is calculated for the different values of the induced strain. We found that tuning of the misfit strain in the film under the dielectric bolometer mode by the proper selection of substrate makes it possible to create the structures with very large values of the pyroelectric coefficient.
