Depolarization field Edemerging from spontaneous polarizationPSis considered to play an essential role in the characteristics of ferroelectrics. For the estimation of Ed, correct dc-permittivityϵdis necessary but is still a controversial issue such as background permittivityϵb. This paper examines the permittivityϵdin the case of 1-dimensional insulating single-domained ferroelectric, by noting thatϵddepends on howPSis defined. This examination shows thatϵdshould be unity when experimentalPSor self-consistentPSis used. Without relying on special theories, a generic consideration based on this results shows that 1-dimensional insulating single-domained ferroelectric having 1st order ferroelectric transition cannot exist thermodynamically.
