The thickness- and orientation- dependences of Curie temperature were investigated for (111) -oriented, (100)-oriented and randomly-oriented 0,07YO(1.5)-0.93HfO(2) films using high-temperature X-ray diffraction to study temperature stability of fe...
Ferroelectricity has been demonstrated in epitaxial 7%Y-doped HfO2 (0.07YO(1.5)-0.93HfO(2), YHO7) films grown by the RF magnetron sputtering method at room temperature without any subsequent annealing. The x-ray diffraction patterns of such films ...
