High-resolution synchrotron X-ray powder diffraction measurement with multiple-detector system has been performed to investigate the scaling effect in ferroelectric PbxSr1-xTiO3 nanoparticles at ambient temperature with various sizes ranging from 10 to 200 nm and various compositions. The peak profiles of the 200 reflections show a large broadening and asymmetry for all particle sizes with decreasing...
The c-axis oriented K3Li2Nb5O15 (KLN) tungsten-bronze thin films have been grown on LaNiO3/Si substrates substrates by RF planar magnetron sputtering. The target used in this study is prepared by sintering pressed powder with potassium and lithium enriched composition, 33 mole% K2CO3 22mole% Li2CO3 and 45 mole% Nb2O5. The optimum sputtering conditions for growing tungsten-bronze structure films are...
Bi4Ti3O12 (BIT) thick films have been successfully prepared on Pt/ZrO2 substrates by the screen printing technique. Pt bottom and Ag top electrodes were also fabricated at 1300degC for 1 h and 850degC for 10 min by screen printing pastes, respectively. The influence of excess Bi2O3 as a sintering aid was investigated in this study. Screen printable pastes were prepared by kneading appropriated proportions...
