“…Which is higher than that of PZT (52/48) films (F D =7.0×10 -6 Pa -0.5 at 1 kHz) [24], and PZT(30/70) films (F D =0.81×10 -6 Pa -0.5 at 1 kHz) [25]; slightly lower than that of sol-gel derived PZT(15/85) films (F D =13 ~ 15×10 -6 Pa -0.5 ) [26]; and lower than that of epitaxial grown PZT(45/55) (F D =20×10 -6 Pa -0.5 ) and PZT(90/10) (F D =17×10 -6 Pa -0.5 ) films [27]. From the results, the dielectric, ferroelectric and pyroelectric properties of the (001)-oriented PSZT film are better than that of the graded PZT film [28].…”

Lead strontium zirconate titanate (Pb0.92Sr0.08)(Zr0.65Ti0.35)O3 (PSZT) thin films were grown on Pt (111)/Ti/SiO2/Si(100) substrates using a simple sol-gel method. X-ray diffraction studies confirmed that all the PSZT films undergone various thermal process show highly preferred (001)-orientation. On the surface image of the thin film, many clusters are found, which are composed by grains in size of 0.5-0.8 mm. Between the clusters, the nano-size grain is about 50-80 nm. The root mean square (RMS) roughness of the film surfaces is 5.1 nm. PSZT thin film exhibit excellent ferroelectric behavior, demonstrated by reproducible hystersis loops with high remnant polarization (Pr =49 μC cm-2) and relative low coercive field (Ec=53.5 kV cm-1). The pyroelectric coefficients (p) were measured, at 26 °C, the p=215 mC m-2 K-1 for PSZT films. The dielectric properties as well as phase transition behavior were characterized and a ferroelectric to paraelectric transition were found in the vicinity of 196 °C.

“…In recent years, the energy manufacturers have been seeking diverse types of the FGMs, in order to improve the performance and efficiency of some of their devices. The FGMs have been strongly used in the energy field [214][215][216][217] including piezoelectric FGMs for the ultrasonic transducers, actuators, damping materials, energy absorption, energy harvesting, thermoelectric converter for energy conversion, solar panels, solar cells, fuel cells, turbine blade coatings and the graded electrode for the production of solid oxide fuels cells [71,213,[218][219][220][221][222][223][224][225][226][227][228][229][230][231][232][233][234][235][236]. Cano et al [218] have studied the growth of hybrid III-V/SiGe solar cells on Si substrates through reverse graded buffers.…”

Functionally graded materials (FGMs) are new materials whose properties change gradually in respect to their dimensions. This group of materials shows a tremendous improvement of previously used composite materials. FGM consists of two or more materials whose combination enables the achievement of specified properties in accordance with the desired application. The article gives an overview of different classifications, various fabrication methods and applications of the FGMs. It could also provide insight and perspective for researchers, university students and research and development teams since it has brought together diverse aspects of FGMs. As mentioned in section two, we took all FGMs fabrication methods under consideration, giving the reader an insight into how to make a product while satisfying the conditions of financial and mechanical efficiency. The classification section specifically goes over structures, types of gradients, sizes/scales, state of matter and finishes with the manufacturing processes. Section two deep dives into the fabrication methods used in the FGMs, which are divided into three sub-sections, including gas-based, liquid-based and solid-based. Lastly, various applications of the FGMs in different fields and industries, namely aerospace, energy, medicine, military, manufacturing and eventually other applications, are demonstrated.

“…The well-crystallized perovskite phase and the crystallographic orientation have been pointed out to play an important role in determining the performance of the PZT films (Tang et al, 2004;Hu et al, 2004;Wang et al, 2002;Gong et al, 2004a), both of which are closely related to the deposition process and post-annealing condition. Indeed, the functional properties of PZT films show great correlation with the specific microstructure with preferred orientation, i.e., texture.…”
