|Abstract:||The dielectric enhancement observed in compositionally graded ferroelectric films is explained by use of a multilayer model. The finite size effect of the ferroelectric layers has been taken into account. This is tackled by the employment of Landau–Ginzburg thermodynamic theory for each layer. The calculated dielectric susceptibility of the graded film reveals significant enhancement for temperatures below the phase transition point, and is greater in a continuously graded film than in one with a step gradient in composition.|
