摘要：

Nb doped barium titanate films were synthesized by r.f magnetron sputtering. As-deposited films were amorphous and started to crystallize around 500°C. The two-stage crystallization observed in DSC studies was explained on the basis of diffusion controlled nucleation and growth of crystallites. Doping of Nb in BT thin films was found to result in lattice expansion and grain refinement. The dielectric constant was found to increase with Nb addition. The lower value of dielectric constant was probably attributed to small grain sizes of Nb doped BT thin films.
