Synthesis and Characterization of Erbium Doped Lead Zirconate Titante Thin Films

Abstract

The present work includes preparation and characterization of polycrystalline complex compounds thin films of (Pb1-zErz)(Zr0.52Ti0.48)1-(z/4)O3 with different erbium concentration (z = 0.05, 0.07, 0.09). Thin films were deposited on nickel /cupper foil substrate by using radio frequency magnetron sputtering technique. Due to the high melting point of ceramic materials, radio frequency magnetron sputtering technique that is employed in the current investigation considers the optimum method compared to other evaporation methods. In order to allow the crystallization into the perovskite phase, the deposited thin films were annealed at 600 ᵒ C using the vacuumed furnace. X-Ray diffraction (XRD) and atomic force microscopy (AFM) were employed to characterize the prepared thin films at room temperature. LCR meter was used to determine the dielectric properties at different temperatures and frequencies. The dielectric constant of prepared thin films was at the range of (372-116), while that of loss tangent was about (0.057-0.011). The results show that the values of dielectric constant increase with increasing the temperature and then suddenly decreased as a result of face transformation in Curie temperature, while the values of loss tangent decreased with an increase in frequency. Moreover, the results showed that the dielectric constant, loss tangent and Curie temperature values were decreased with increasing of the erbium content.

Mechanical Properties of 3D-Printed PETG Samples: The Effect of Varying Infill Patterns

“…Most importantly, the properties of additively manufactured components using 3D printing technique are affected by the filling factor, print and raster direction, and layer-to-layer thickness [30]. There is a great deal of studies [31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49] analyzing the effect of various variables on mechanical characteristics, especially tensile characteristics. Camposeco-Negrete [50] analysed the impact of layer print size, infill shape, raster direction of 3D-printed parts using Taguchi and ANOVA methods.…”
