摘要: The microstructure and electrical properties of P(VDF-TrFE)/Bi3.5Nd0.5Ti3O12 bi-layer composite ferroelectric thin films deposited on Pt/Ti/SiO2/Si using two successive spin coatings were investigated. It shows the pores in Bi3.5Nd0.5Ti3O12 (BNT) effectively suppressed by presence P(VDF-TrFE) copolymer SEM. ferroelectric, leakage dielectric with different thickness ratio BNT measured. With increasing P(VDF-TrFE), remnant polarization, coercive electric field, current density constant all decreased (except pure film). Results indicate that key improved a little loss which infers potential application filed memory.
