Images of crystals grown during the First International Microgravity Laboratory (IML-1) flight in 1992 were taken and compared with others of terrestrially-grown crystals. The local acceptance angle for diffraction from the uncut TGS crystal grown on the IML-1 mission was found to be 1-2 arc seconds, indicating extraordinary crystal uniformity. The only inclusions visible in the topographs were polystyrene particles intentionally introduced into the growth solution of the space crystal. No demarcation was seen between the terrestrial seed and the new growth of the crystal grown in space. TGS crystals grown on the ground were found to have edge dislocations near the cleaved surface. The results of the topographic studies of the space- and ground-grown crystals are discussed and their implications identified.","PeriodicalId":14772,"journal":{"name":"ISAF '96.

The uniformly polarized films were locally polarized in the opposite direction with a metallic electrode as well as with an electron beam in the SEM. The surface potential resulting from the latent charge image at the film surface was measured after polarization and after contrast enhancement by corona charging. Furthermore, the potential contrast could be visualized in the SEM at small accelerating voltages and minimal sample currents. The depth profile of the polarization perpendicular to the film surface was measured by the pyroelectric laser intensity modulation method (LIMM). The influence of film inhomogeneities on the surface potential is discussed.","PeriodicalId":14772,"journal":{"name":"ISAF '96.

The electrical admittance, mechanical displacement, and blocking force of these transducers have been found to be highly dependent on the magnitude of driving field. The resonant frequency and mechanical quality factor of bending vibrations for all but shear-mode actuators decreases significantly with increasing driving field. Analysis shows that despite a large variation in the quasi-static electrical admittance and reduced tip displacement of bimorph, unimorph, and RAINBOW cantilevers with driving field, their ratio is almost a constant, which characterizes the ratio of dielectric permittivity /spl epsi//sub 33//sup T/ to piezoelectric coefficient d/sub 31/.","PeriodicalId":14772,"journal":{"name":"ISAF '96.

The films were deposited using the doctor blade method and rapid furnace-annealed at 600/spl deg/C. Single layer film thickness was up to 1 /spl mu/m; with repeated deposition procedures overall film thicknesses of about 4 /spl mu/m were obtained. XRD measurements show a perovskite phase formation; no phases due to chemical interactions with the substrate were found. By TEM investigations grain sizes up to 1 /spl mu/m were found, pores of about 50 nm in diameter were detected within the grains. Small signal dielectric measurements showed permittivity values of about 400, independent on film thickness. After postannealing the samples at 700/spl deg/C the permittivity slightly increases. Hysteresis measurements show decreasing coercive field values with increasing film thickness; typical coercivity values are in the range of 10 V//spl mu/m. Polarization values were found to be about 35 /spl mu/C/cm/sup 2/, for postannealed samples a somewhat higher polarization was obtained. A frequency dependence was found by large signal dielectric measurements, resulting in a broadening of the hysteresis loops with decreasing frequency due to conductivity. Fatigue measurements show a decay of the ferroelectric properties after 10/sup 4/ poling cycles.","PeriodicalId":14772,"journal":{"name":"ISAF '96.
