Influence of processing conditions on the structure, composition and ferroelectric properties of sputtered PZT thin films on Ti-substrates

Chemistry of surface nanostructures in lead precursor-rich PbZr0.52Ti0.48O3 sol–gel films

“…6 in binding energy, confirming the rigid nature of the etching induced shift. In the Pb 4f spectrum a new component at lower binding energy appears, and corresponds to metallic Pb 0 at 136.07 eV such as described by Lu and Zhu [28]; similarly, a partial reduction of Ti is evidenced with an additional component to lower binding energy (Ti II ) at 456.64 eV), as also observed previously [17]. Both results provide chemical confirmation of the surface reduction after IBE.…”

“…The absence of a clear grain structure is due to the IBE-induced amorphization of the surface, well-known in the literature [24,20,26]. IBE can also reduce the surface [17,26] in which case one would expect a shift in the electronic levels similar to that induced by n-type doping of semiconductors. In order to compare the core level spectra before and after IBE we must first correct the energy scale for the electronic effect resulting from n-doping.…”

“…Pyrochlore is produced mainly at lower temperature and vanishes as temperature increases [9,12,10]. However, other possible phases have also been suggested, such as PbO [11], fluorite [16,17] or ZrO 2 [18]. Therefore, the first question is to determine the chemical nature of eventual secondary phases at the surface of sol-gel PZT.…”

Pulsed laser assisted growth of aligned nanowires of WO3: role of interface with substrate

“…34 To the best of the present authors' knowledge, no detail work exists regarding the tuning of the growth morphology of WO 3 nanowires on platinised-silicon substrates by controlling the growth parameters (mainly laser energy) especially in PLD. 37 In that regards our study provides an in-depth knowledge regarding the material substrate interface that ultimately controls the material physical properties. Therefore, many efforts have been focused on the improvement of synthetic routes of 1D WO 3 nanostructures such as nanowires and exploration of the 1D direction crystal growth mechanism.…”

Synthesis and Characterization of Lead Zirconate Titanate Nanofibers Obtained by Electrospinning

“…And the advantages of PZT material devices are high sensitivity, fast response, high flexibility, and increased anisotropy . PZT powders and thin films have been synthesized in many different ways including radio frequency magnetron sputtering, laser ablation, chemical vapor deposition, sol–gel, metallo‐organic decomposition, and ball milling . However, PZT fibers have been fabricated by a few methods such as metallo‐organic decomposition, electrospinning, and hydrothermal synthesis .…”
