Properties of Barium Cerate-Zirconate Thin Films

Abstract

In this work, we review several experimental results showing the electrical properties of barium cerate-zirconate thin films and discuss them in view of the possible influence of various factors on their properties. Most of the presented Ba (Ce, Zr, Y) O3 thin films were formed by the pulsed laser deposition (PLD) technique, however thin films prepared using other methods, like RF magnetron sputtering, electron-beam deposition, powder aerosol deposition (PAD), atomic layer deposition (ALD) and spray deposition are also reported. The electrical properties of the thin films strongly depend on the film microstructure. The influence of the interface layers, space-charge layers, and strain-modified layers on the total conductivity is also essential but in many cases is weaker.

Highly Conductive Ceramics with Multiple Types of Mobile Charge Carriers

“…The review conducted by Winiarz et al [4] focuses on protonic ceramic cells, specifically the electrolyte materials (e.g., Ba(Ce,Zr,Y)O 3-d ) and thin films formed by the pulsed laser deposition (PLD) technique, as well by as using other methods such as RF magnetron sputtering, electron-beam deposition, powder aerosol deposition (PAD), atomic layer deposition (ALD), and spray deposition. Interestingly, the factor that impacts most of the electrical properties of thin films is the film microstructure.…”

In situ neutron diffraction study of BaCe0.4Zr0.4Y0.2O3−δ proton conducting perovskite: insight into the phase transition and proton transport mechanism

“…[23][24][25][26][27] Thin lms based on Ba(Ce,Zr)O 3 perovskites were also explored and characterized. 28 Ab initio, rst-principles, (kinetic) Monte-Carlo, density functional theory (DFT) investigations, quantum molecular dynamics simulations, and work combining experimental and theoretical data have been performed in order to understand, predict the properties and improve and optimize the development of these materials. [29][30][31][32][33][34][35][36][37][38][39][40][41] Advanced manufacturing techniques are promising due to their signicant commercial future for the fast and economic production of protonic ceramic electrochemical cells.…”

The Role of Strain in Proton Conduction in Multi-Oriented BaZr0.9Y0.1O3−δ Thin Film

“…Recently, highly conductive and dense thin films of electrolytes with a controllable microstructure have been fabricated using pulsed laser deposition (PLD). − As compared to the bulk form, thin films provide more degrees of freedom to tune the physical properties of the material via controllable strain, thickness, and defect engineering. − In addition, thin films can allow for the growth with different crystallographic orientations to maximize material properties for particular purpose . Moreover, modern technology requires the downscaling of device size that enhances the importance of thin-film fabrication.…”
