YO1.5-doped HfO2 films were deposited on yttria-stabilized zirconia substrates by RF magnetron sputtering at room temperature and under various atmosphere conditions. The deposited films were treated by rapid thermal annealing under both O-2 and N...
The thickness dependences of the crystal structure and electric properties of (111)-oriented epitaxial 0.07Y(2)O(3)-HfO2 (YHO7) ferroelectric films were investigated for the film thickness range of 10-115 nm. The YHO7 films were grown by pulsed la...
The dependence of applied rectangular pulses with various widths on the crystal structure change was investigated by time-resolved synchrotronbased X-ray diffraction measurement. A (001)-oriented epitaxial Pb(Zr0.5Ti0.5)O-3 film of 2.1 mu m thickn...
