a Static bias field dependence of the dielectric permittivity of a BSRO/BST80/BSRO/SSO capacitor collected with various modulation amplitudes of measurement voltage. b Dielectric permittivity of the BSRO/BST80/BSRO/SSO and BSRO/BST80/BSRO/KTO capacitors as function of modulation amplitude, collected at zero static bias voltage. c Temperature dependence of the dielectric permittivity, loss and tunability of BSRO/BST80/BSRO/SSO capacitor measured at different modulation amplitudes as denoted.
