We have developed a calorimetric sensor utilizing a thermoelectric device supported on a planar alumina substrate. By using a highly selective carbon monoxide (CO) oxidation catalyst and a non-selective platinum (Pt) catalyst, the device can be built

We have studied the temperature dependence of the Raman spectra of ceramic bulk and thin-film samples of polycrystalline ${\mathrm{Ba}}_{1\ensuremath{-}x}{\mathrm{Sr}}_{x}{\mathrm{TiO}}_{3}$ $(x=0,$ 0.1, 0.2, and 0.3) in the range between room temper

The diffuse-phase-transition class of ferroelectric materials allows the fabrication of films graded in composition: the consequence of which is an attendant gradient in electric dipole moment density. Alternating electric-field excitation of these g

Ferroelectric thin films (∼1.2 μm) of BaxSr1−xTiO3 with gradients in composition normal to the growth surface were formed on platinum substrates by metalorganic decomposition. Effective (pseudo) pyroelectric coefficients as large as 0.06 μC/cm2

Thin films of BaxSr1−xTiO3 (x = 0.7, 0.8, 0.9, and 1.0) were prepared by metalorganic decomposition (MOD). The relative permittivity, dissipation, polarization, resistivity, and grain size of these films were studied as a function of composition an

Layer type Aurivillius compounds of complex ferroelectric bismuth oxides have become important as thin films for nonvolatile, random-access memories(DRAMS). This paper reports the investigation of the formation of these compounds and their electrical

Potassium tantalum niobate (KTN) films, 10- mu m thick, with a nominal Curie temperature of -20 degrees C were formed on polished platinum-coated sacrificial yttria substrates by metalorganic deposition (MOD). These KTN films were used to fabricate f
