The microstructure and preferred orientations of rapid thermally annealed Pb(Zr0.53, Ti0.47)O3 films, deposited on Pt/Ti/SiO2/Si electrode/substrates by solution-gel spinning, have been investigated using analytical and high-resolution electron microscopy ...
An amperometric microsensor for the detection of trace metals in the low or sub nanomolar range is presented. It is obtained by successively evaporating iridium (2000 Å) and Si3N4 (2000 Å) on a silicon wafer, followed by a photolithographic pattering proce ...
Electrode stability, interdiffusion, phase purity and deviation from stoichiometry at the PZT-electrode interface are key issues in PZT thin film integration. This article highlights the use of transmission electron imaging combined with energy dispersive ...
Results are presented which are geared towards an understanding of the influence of powder formation during film growth. Plasma chemistry is correlated with the morphology, structure (inferred through infrared spectroscopy, scanning electron microscopy and ...
Single crystals of layered semiconductors such as WS2 and MoS2 have already proven their efficiency as active elements in photovoltaic cells. Due to their high optical absorption coefficient in the visible range, these materials could be used in the form o ...
ZnO and AlN, which exhibit the wurtzite structure, were deposited onto metal coated SiO2 substrates by sputtering. X-ray diffraction (XRD) indicated that the films contained no second phases and exhibited an [0001] texture. Transmission electron microscopy ...
The mechanisms of strain relief in submonolayer heteroepitaxy of Cu/Ni(100) are studied using variable temperature scanning tunneling microscopy and high resolution low energy electron diffraction. It is demonstrated that pseudomorphic copper islands, as t ...
We demonstrated that polycrystalline cesium iodide (CsI) on large area Ni/Au coated printed board provides a quantum efficiency (QE) higher by a factor of 2 than the films deposited on the standard Cu/Au printed circuits. This is the most important result ...
Superconducting Bi-2212/Ag monocore wires of 0.65, 1.0, 1.2 and 1.5 mm diameter have been fabricated by the powder-in-tube method. The critical current densities increase with decreasing wire diameters. For short specimens of 0.65 mm diameter, maximum crit ...
Pb1-xCaxTiO3 thin films with x = 0-0.3 for pyroelectric applications were deposited on platinized silicon wafers by chemical solution processing. Ca-substitution for Pb in PbTio(3) results in a reduced cia ratio of the unit cell, which, in turn, leads to b ...
