“…4, the good orientation of the films was also supported by rocking curve analysis [10]. The full width at half maximum (FWHM) of the (100) diffraction of the films annealed at 450, 500, 550 and 600 1C were 12.4, 7.6, 9.5, and 13.2, respectively.…”

“…2(c)], and it cannot provide nucleation sites, which results in the lower remnant polarization. But the E c is much lower compared with PNZT film without seed layer, this is because that the PLCT seed layer exhibits lower E c and lower curie temperature, 28,29 and the thick PLCT seed layer at interlayer may change the composition of PNZT film, which results in lower E c of the PNZT film. Furthermore, although the PNZT thin film with 10 nM PLCT seed layer is still (111)-oriented, the (100) peak is obviously observed (see Fig.…”

A series of highly (111)‐oriented tetragonal Nb‐doped Pb(Zr0.2Ti0.8)O3 (PNZT) films with Pb0.8La0.1Ca0.1Ti0.975O3 (PLCT) seed layers of variant thickness were deposited on the Pt(111)/Ti/SiO2/Si substrates by sol–gel processing. It was found that the PLCT seed layer played a significant role on the microstructures and electrical properties of the PNZT films. The PNZT thin film with 5‐nM‐thick PLCT seed layer displayed enhanced electrical properties such as a large remnant polarization Pr (60 μC/cm2) and a low coercive field Ec (51 kV/cm) at room temperature. The enhancement of electrical properties can be attributed to the rough surface structures of the PLCT seed layer, which offered nucleation sites to reduce the crystallization activation energy of PNZT films and thus facilitated the polarization response. The PLCT seed layer also can act as a capacitive interface layer, reducing or compensating for the vacancy‐type defects of PNZT film effectively, which results in the relatively low current density of PNZT film. These results indicate that the fabricated film is a good candidate for high‐density memories application.
