Rare earth-doped ceria thin films are currently thoroughly studied to be used in miniaturized solid oxide cells, memristive devices and gas sensors. The employment in such different application fields derives from the most remarkable property of this material, namely ionic conductivity, occurring through the mobility of oxygen ions above a certain threshold temperature. This feature is in turn limited by the association of defects, which hinders the movement of ions through the lattice. In addition to these issues, ionic conductivity in thin films is dominated by the presence of the film/substrate interface, where a strain can arise as a consequence of lattice mismatch. A tensile strain, in particular, when not released through the occurrence of dislocations, enhances ionic conduction through the reduction of activation energy. Within this complex framework, high pressure X-ray diffraction investigations performed on the bulk material are of great help in estimating the bulk modulus of the material, and hence its compressibility, namely its tolerance toward the application of a compressive/tensile stress. In this review, an overview is given about the correlation between structure and transport properties in rare earth-doped ceria films, and the role of high pressure X-ray diffraction studies in the selection of the most proper compositions for the design of thin films.

Degree Of Orientation

ABSTRACTA new metallo-organic spin-on technique is described for producing thin films of the high temperature perovskite superconductors, LnBa2Cu3O7−x, where Ln represents a rare earth element. Pyrolysis of the spin-coated films leads to black films up to several microns thick whose degree of orientation is a function of the processing temperature and duration. Representative films of YBa2Cu3O7−x on MgO begin to exhibit orientation with the c-axis perpendicular to the film at heat treatments above 900 'C. The superconducting behavior of a highly oriented film produced at 990 ° C is characterized by Tc (onset) = 89 K, Tc (R=0) = 77 K and Jc = 104 amp cm-2 at 65 K.

Combinatorial Strategy

Interests in finding new rare-earth doped oxide materials able to remotely sense high temperature have been intensifying in recent years. If applied, advanced combinatorial strategy for materials science should be efficient in finding a suitable host material, and in optimizing a rare earth ion’s doping concentration, luminescence intensity, emission lifetime, etc. This research demonstrates our preliminary effort to apply the advanced combinatorial material strategy to this new area of finding materials for sensing high temperatures.
