We describe the application of misted chemical solution deposition (CSD) techniques to processing of ferroelectric-filled porous silicon photonic devices and of novel precursor medium- and high-dielectric constant films for gate oxide and memory appl

We discuss several new aspects of ferroelectric thin-film physics: (1) The apparent surface ordering in polymeric films of the PVDF family and the likelihood of domain-free switching; (2) coherent nucleation of nano-domains in front of a larger advan

The effect of A-cation size on the structural and electrical properties in a family of ferroelectric tetragonal tungsten bronzes (TTBs) Ba4R(0.67)□(1.33)Nb10O30 (R = La, Nd, Sm, Gd, Dy and Y; □ = vacancy) was investigated. In each case, the cryst

The electrical properties of Ba1−xLaxTi1−x/4O3 ceramics where x≤0.20 were investigated by impedance spectroscopy after heat treatment in O2, Ar and air at 1350°C. Samples heated in O2 were electrically insulating with very high maximum permitt

The electrical properties of two single-phase, lanthanum-doped BaTiO3 compositions, x= 0.03 and x= 0.20, in Ba1–xLaxTi1–x/4O3 were investigated by impedance spectroscopy after heat treatment in oxygen, argon, and air at 1350°C. Samples heated in

The mechanism of doping BaTiO3 with La has been investigated by a combination of X-ray diffraction, electron probe microanalysis, scanning and transmission electron microscopy and impedance measurements. Phase diagram results confirm that the princip

Single phase La-doped BaTiO3 with the formula Ba1−xLaxTi1−x/4O3: 0⩽x⩽0.20 was prepared by solid state reaction of oxide mixtures at 1350 °C, 3 days, in O2. The tetragonal distortion in undoped BaTiO3 decreased with x and samples were cubic f

Spark-plasma-sintering (SPS) has been applied to BaTiO3 to prepare dense ceramics consisting of submicrometre-sized powder. Relatively dense (typically 97% of the theoretical X-ray density) pellets with an average grain size remaining similar to that
