| contents | An attempt has been made to synthesize (Ca0.4Sr0.6)Bi4Ti4O15(CSBT) thin film using pulsed laser deposition (PLD) and successfully optimized the deposition conditions. A good quality film with the desired phase is obtained at a substrate temperature of 650 oC based on phase, composition and morphology studies. Highly c-axis oriented films with average thickness 330-400 nm and an average grain size 40-65 nm has been found. Piezoresponse force microscopy (PFM) showed a complete domain reversal using switching spectroscopy. A comparatively high effective d33* value as ~120 pm/V has been achived. The results suggest that CSBT has a great potential in electromechanical applications. |
