title = "Coupling of the remanent polarisation in thin film oxide ferroelectrics with nematic liquid crystals",
abstract = "The technique of domain visualisation, revealed by a film of nematic liquid crystal (NLC) on a ferroelectric crystal substrate, is demonstrated for the first time to be applicable to thin films of lead zirconate-lead titanate (PZT) ferroelectric ceramics. PZT film thicknesses <1 μm were deposited on indium tin oxide coated glass substrates. Commercially available NLC materials with positive dielectric anisotropy were employed. The electro- optic properties of devices incorporating the ferroelectric ceramic and NLC are reported. The poled PZT grains induce a local Freedericksz transition in the NLC and it is proposed that the ferroelectric NLC interaction is primarily due to the depolarisation field due to the ferroelectric remanent polarisation.",
