Perovskite ferroelectric PNN ceramics have been obtained from oxides by sintering in air, using a two-stage process with corundum Ni4Nb2O9 precursor. Under suitable firing condition, XRD analysis revealed that the ceramics consist of 100% perovskite phase. The SEM, EDX, and XPS techniques were employed to investigate the chemical composition of the surfaces of the PNN ceramics. Fluctuation in chemical composition, precipitation of NiO and the Pb-Ni-Nb-O phase different from perovskite were found.

Stage Process

CuInSe 2 thin films were deposited on soda lime glass substrates following a two-stage process which includes a chemical reaction between thin films of Cu and In x Se y, followed by thermal annealing in a Se environment. Initially, the Cu layer is deposited on the glass substrate by DC magnetron sputtering in the S-gun configuration, and subsequently the In x Se y layer is deposited by the closed spaced sublimation (CSS) method. The influence of the deposition method and of the main deposition parameters of the precursor layers (Cu and In x Se y) on the phases present in the resulting compound were studied by means of X-ray diffraction (XRD) and optical gap (Eg) measurements. The conditions for growing CuInSe 2 thin films in the chalcopyrite phase were determined through an exhaustive parameter study. The study revealed that the thickness of the precursor layers and the selenization conditions affect the phase in which the CuInSe 2 compound grows.
