dc.description.abstract | A monolayer of Sr2Nb3O10 (SNO) is deposited on the Pt/Ti/SiO2/Si (Pt-Si) or Pt/Ti/polyimide (Pt-PI) substrate by using the Langmuir-Blodgett method and employed as a seed-layer for the growth of a crystalline (Na1-xKx)NbO3 (NKN) film at 350 degrees C. The crystalline NKN film is grown along the [001] direction on the SNO/Pt-Si (or SNO/Pt-PI) substrate. Due to the presence of oxygen vacancies in the SNO seed-layer, the NKN film exhibits low ferroelectric properties and large leakage current. To ameliorate these properties, the SNO/Pt-Si substrate is annealed in a 50 Torr oxygen atmosphere at 300 degrees C, which removes the oxygen vacancies. Consequently, the NKN film deposited on this substrate exhibits promising electrical properties, namely a dielectric constant of 278, dissipation factor of 1.7%, a piezoelectric constant of 175 pmV(-1), and a leakage current density of 6.47 x 10(-7) Acm(-2) at -0.2 MV center dot cm(-1). Similar electrical properties are obtained from the NKN film grown on the flexible SNO/Pt-PI substrate at 350 degrees C. Hence, the NKN films grown on the SNO seed-layer at 350 degrees C can be applied to electronic devices with flexible polymer substrates. | - |
