Scalable Oxygen-Ion Transport Kinetics in Metal-Oxide Films: Impact of Thermally Induced Lattice Compaction in Acceptor Doped Ceria Films
نویسندگان
چکیده
Decreasing the dimensions of ionic conductors to the nanoscale has enabled the realization of new electrochemical devices integrated on Si-based and other microsystems. These comprise fast ionic conducting electrolytes for energy-applications such as micro-fuel cells [ 1,2 ] and batteries, [ 3 ] gas conversion/reformation catalysts, [ 4,5 ] sensors, [ 6 ] and for redox-reaction based resistive memories. [ 7,8 ] A key objective for these devices is to simultaneously achieve high device density per chip together with enhanced reaction and transport kinetics. Among various mixed ionic and electronic conducting (MIEC) oxides, doped ceria nano-scale fi lms are of interest for a broad set of these microsystem based applications. [ 6,9,10 ]

Dislocations Accelerate Oxygen Ion Diffusion in La0.8Sr0.2MnO3 Epitaxial Thin Films
Revealing whether dislocations accelerate oxygen ion transport is important for providing abilities in tuning the ionic conductivity of ceramic materials. In this study, we report how dislocations affect oxygen ion diffusion in Sr-doped LaMnO3 (LSM), a model perovskite oxide that serves in energy conversion technologies. LSM epitaxial thin films with thicknesses ranging from 10 nm to more than ...
متن کاملPhoto-excitation effects on oxide-ion conductors: case study of zirconia thin films Investigators
Enhanced grain growth in ultra-thin yttria-doped-zirconia (YDZ) films synthesized under ultraviolet (UV) irradiation is reported. The mean grain size in UV-activated 7.5 mol % yttria doped zirconia films nearly 56 nm thick increased to 85 nm upon annealing in an oxygen-rich ambient at 900 C for one hour, while in thermally grown YDZ they grew only to ~15 nm under identical annealing conditions....
متن کاملElectrochemically Deposited Ceria Structures for Advanced Solid Oxide Fuel Cells
As the pursuit towards emissions reduction intensifies with growing interest and nascent technologies, solid oxide fuel cells (SOFCs) remain an illustrious candidate for achieving our goals. Despite myriad advantages, SOFCs are still too costly for widespread deployment, even as unprecedented materials developments have recently emerged. This suggests that, in addition to informed materials sel...

Zn1-x Ni x O (x = 0.03 ÷ 0.10) and Zn1-x Fe x O (x = 0.03 ÷ 0.15) thin films were synthesized by sol-gel method. The structure and the surface morphology of zinc oxide thin films doped with transition metal (TM) ions have been investigated by X-ray diffraction (XRD) and atomic force microscopy (AFM). The magnetic studies were done using vibrating sample magnetometer (VSM) at room temperature. E...
متن کاملStrongly enhanced oxygen ion transport through samarium-doped CeO2 nanopillars in nanocomposite films
Enhancement of oxygen ion conductivity in oxides is important for low-temperature (<500 °C) operation of solid oxide fuel cells, sensors and other ionotronic devices. While huge ion conductivity has been demonstrated in planar heterostructure films, there has been considerable debate over the origin of the conductivity enhancement, in part because of the difficulties of probing buried ion trans...
