                      (BST) thin films with thicknesses ranging from 100 to 250 nm
                      is investigated in the frequency range from 500 MHz to 40
                      GHz by impedance spectroscopy of integrated BST capacitors.
                      The dielectric spectra of the films exhibit resonance
                      phenomena in the 4-7 GHz range when a bias field is applied.
                      It is shown that the main controlling parameter of the
                      resonance frequency is the film thickness. Calculations
                      based on the strong electrostrictive activity of the BST
                      films underline the assumption that the emission of plane
                      acoustic waves is the underlying mechanism for this
                      behavior. (C) 2004 American Institute of Physics.},
