Transparent conductive electrodes are important components of thin-film solar cells, light-emitting diodes, and many display technologies. Doped metal oxides are commonly used, but their optical transparency is limited for films with a low sheet resistance. Furthermore, they are prone to cracking when deposited on flexible substrates, are costly, and require a high-temperature step for the best...

A novel method for the deposition of RuO(2) from RuO(4)(g) on diverse metal oxides has been developed by grafting dopamine onto the otherwise un-reactive metal oxide surface. Oxygen evolution reaction on TiO(2) and the photoelectrochemical improvement of WO(3) by deposition of RuO(2) are just a few examples where this novel deposition method can be used.

A mechanochemical synthetic method of preparing LiCoO2 coated by MOF-derived metal oxide composites is introduced. Mono-dispersed ZrO2 and Al2O3 are applied as protection layers. These composites show 148 mA h g(-1) at a current density of 2325 mA g(-1) and excellent thermal stability (55 °C).

An all-optical terahertz absorption technique for nondestructive characterization of nanometer-scale metal oxide thin films grown on silicon substrates is described. Example measurements of laser-deposited TiO2 and atomic layer-deposited films of HfO2 are presented to demonstrate applicability to pure Y2O3, Al2O3, and VOx and mixed combinatorial films as a function of deposition conditions and ...

The influence of quenched disorder on the competition between ordered states separated by a first-order transition is investigated. A phase diagram with features resembling quantum-critical behavior is observed, even using classical models. The low-temperature paramagnetic regime consists of coexisting ordered clusters, with randomly oriented order parameters. Extended to manganites, this state...

With large spin-orbit coupling, the electron configuration in d-metal oxides is prone to highly anisotropic exchange interactions and exotic magnetic properties. In 5d(5) iridates, given the existing variety of crystal structures, the magnetic anisotropy can be tuned from antisymmetric to symmetric Kitaev-type, with interaction strengths that outsize the isotropic terms. By many-body electronic...

We observed two long-range-ordering structures of oxygen vacancies, one in every tenth plane of (33j0) and another in every fourth plane of (11j2) in R-Fe2O3 nanowires and nanobelts synthesized under the same conditions. Interestingly, both types of oxygen-vacancy structures found in different nanowires have an equivalent ordering distance of 1.45 or 1.47 nm and were parallel to the growth dire...

A facile method is reported for the preparation of chain-like nanostructures by anisotropic self-assembly of TiO(2) and SnO(2) nanoparticles with the aid of a block copolymer in an aqueous medium. Well-defined crystallographic orientations between neighbouring nanoparticles are observed in TiO(2) nanochains, which is important for tailoring the grain boundaries and thus enhancing charge transport.

Monocrystalline mesoporous BiFeO3 crystals were obtained via a multi-step single-crystal to single-crystal transformation of a coordination polymer, Bi[Fe(CN)6]·4H2O. This unique transformation process significantly decreased the crystallization temperature of perovskite oxide without losing high crystallinity.

The newly developed scientific complementary metal oxide semiconductor (sCMOS) cameras are capable of realizing fast single molecule localization microscopy without sacrificing field-of-view, benefiting from their readout speed which is significantly higher than that of conventional charge-coupled device (CCD) cameras. However, the poor image uniformity (suffered from fixed pattern noise, FPN) ...
