Electrical And Optical Properties Of A Kind Of Ferroelectric Oxide Films Comprising Of Pbzr0.4ti0.6o3 Stacks

A type of ferroelectric oxide films, consisting of three PbZr0.4Ti0.6O3 stacks with different periodic thicknesses, has been designed and fabricated on F-doped transparent conductive tin oxide substrates by using one single precursor solution and spinning-coating process. These films exhibit superior ferroelectric, dielectric, and optical performance. Each PbZr0.4Ti0.6O3 multilayer has a high reflectivity band with similar to 110 nm photonic band width and average reflectivity of >80%, a dielectric constant of 530 and dielectric tunability of similar to 28% at 1MHz, a remnant polarization of 36 mu C/cm(2), and a polarization loss of <5% after 10(9) polarization switching cycles, rendering their perspective application in photonic band-gap engineering, microwave tunable devices, and integrated optoelectronics.
