| Abstract: | The enhancement of Piezo response and local ferroelectric behavior of PVDF-Bi25FeO40 composite thin films are investigated using piezo force microscopy (PFM) technique. The self-assembled composite nanodots thin films are prepared by spin coater with PVDF and Bi25FeO40 nano powder solution mixture. The structural and morphology characteristics are analyzed by FTIR-ATR and Atomic force microscopy. The surface microstructure, confined domain structure, its piezo, ferro electricity behavior, its corresponding d33 coefficient are explored with PFM under no poling and poling with external DC bias, AC bias and various drive frequencies. The d33 coefficient varies from 14 to 17 pm/V by adding of 5 wt% of Bi25FeO40 to PVDF than pristine PVDF nanodots made under same condition. [ABSTRACT FROM AUTHOR] |
