Evolution of the crystalline structure in (Bi0.5Na0.5)1-xBa x TiO3 thin films around the Morphotropic Phase Boundary

Pérez Mezcua, Dulce Calzada, M.L. Bretos Ullívarri, Iñigo

El (Bi0.5Na0.5)1-xBax TiO3 (BNBT), considerado un posible candidato sin plomo para substituir al Pb(Zrx,Ti1-x)O3 (PZT), presenta una frontera de fase morfotrópica donde se da la coexistencia de las estructuras tetragonal y romboédrica. En este trabajo, se han fabricado láminas delgadas de BNBT por depósito químico de disoluciones (CSD) con...

Morphotropic Phase Boundary in Solution-Derived (Bi0.5Na0.5)1 – xBaxTiO3 Thin Films: Part I Crystalline Structure and Compositional Depth Profile

Pérez Mezcua, Dulce Sirera Bejarano, Rafael Bretos Ullívarri, Iñigo

In this work, ferroelectric (Bi0.5Na0.5)1 – xBaxTiO3 thin films were fabricated by chemical solution deposition (CSD) with compositions x = 0.050–0.150. Stoichiometric thin films (here-inafter BNBT) and others containing 10 mol% excesses of Bi3+ and Na+ (BNBTxs) were spin coated onto Pt/TiO2/ SiO2/(100)Si substrates and crystallized by rapid...
