  5. 5. Tunable Bulk Acoustic Wave Resonators Based on BaxSr1-xTiO3 Thin Films

    University dissertation from Linköping : Linköping University Electronic Press

    Author : John Berge; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; piezoelectric resonators; bulk acoustic wave devices; field induced piezoelectric effect; tunable devices; ferroelectric 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.
