Stability of the ferroelectric phase and its size dependence are investigated by incorporating the semiconductor properties of the ferroelectric into a thermodynamic Landau theory. The semiconductivity of the ferroelectric was found to stabilize the ferroelectric phase much more effectively than the inhomogeneity(∇P)- and multidomain-effects. The theory explains well the experimental surface charge in ferroelectric FET and its temporal stability.
