4. Tunable Bulk Acoustic Wave Resonators Based on BaxSr1-xTiO3 Thin Films
Abstract : The main focus of this thesis is the study of a novel component based on ferroelectric BaxSr1−xTiO3 thin films – the tunable thin film bulk acoustic resonator (TFBAR). The tunable TFBAR utilizes a dc field induced piezoelectric effect in the ferroelectric film, in contrast to conventional fixed frequency TFBARs, widely used for filtering applications in wireless communication systems,which are based on ordinary piezoelectric materials.
