Summary: Lithium zirconium phosphate (LiZr2P3O12) thin films were prepared using a chemical solution deposition approach at temperatures between 700°C and 775°C, with post-annealing significantly affecting the crystallinity, grain size, and ion conductivity properties of the films. Single high-temperature annealing improved ion conductivity, while per-layer annealing showed a more complex effect with an initial increase followed by a decrease in ion conductivity. These results suggest that different post-deposition processing methods can greatly influence the ion conducting properties of LiZr2P3O12 thin films.

Summary: Amorphous Ce2Ti2O7 (CTO) thin films were prepared on an ITO/glass substrate using the sol-gel method, and the effects of various factors on the resistance-switching characteristics of the device were studied.

Summary: Semiconductor photocatalysts, such as SrTiO3 nanoparticles, are widely used for degrading organic pollutants in water through photocatalysis. This study focuses on the photocatalytic degradation of methyl orange and methylene blue using SrTiO3 as a photocatalyst in de-ionized and hard water. The addition of Ag and Au nanoparticles to SrTiO3 enhanced its photocatalytic activity, with Au yielding better results. However, bare SrTiO3 and its composites did not show any degradation of methyl orange in both de-ionized and hard water.

Summary: By utilizing ultraviolet-responsive gallium nitride (GaN) and infrared-activated tin selenide (SnSe), a broadband heterojunction-based optical detector was fabricated, combining the detection capabilities of GaN in the ultraviolet to visible range and SnSe in the visible to shortwave-infrared range. The detector exhibited high responsivity, low dark current, and edge contact geometry for direct access to the heterostructure interface of both materials. The device showed excellent performance across the ultraviolet-C to shortwave-infrared region, with a maximum responsivity of 128 AW-1, a noise equivalent power of 5.2 x 10-14 WHz- 1/2, and a quantum efficiency of 5 x 104% for ultraviolet illumination, and a maximum responsivity of 6.06 AW-1 and noise equivalent power of 1 x 10-12 WHz- 1 for infrared illumination. This research opens up new possibilities for wideband detection in optoelectronic applications utilizing heterostructure-based devices.

Summary: The present study demonstrates the tuning of structural, topography, and luminescence properties of 30 keV Li-ion implanted (K, Na)NbO3 thin films synthesized using RF sputtering. The results show that the crystallinity and morphology of the films are affected by Li-ion implantation, with a decrease in crystallinity and a change in the morphology. The transmittance of the films is minimally improved, while the optical band gap and the relative PL intensity in the ultraviolet region are increased with the ion fluence. The carrier lifetime is also increased after ion implantation.

Summary: III-nitrides are versatile materials that have the potential to be used in a wide range of interdisciplinary applications. However, the quality and performance of conventional III-nitride devices are constrained due to lattice and thermal mismatches with the substrate. This issue can be addressed by growing III-nitrides on unconventional substrates, which have significantly reduced mismatches and potential advantages such as wavelength tunability and lower efficiency droop. This perspective critically examines recent advances in III-nitride epitaxy on unconventional substrates and explores the challenges and constraints of practical implementation.

Summary: We present an efficient method of growing infrared (IR) sensitive mixed phase of V7O16 and V2O5 thin films at low temperatures. The mixed phase can be stabilized by annealing amorphous VxOy at 300-400 degrees C, and is fully converted into V2O5 after annealing at 450 degrees C. The optical transmission of the films increases with the content of V2O5, while the electrical conductivity and optical bandgap decrease. The IR sensitivity is explained by plasmonic absorption by the V7O16 degenerate semiconductor.

Summary: Although molecular dynamics (MD) simulation is a powerful tool for investigating the atomic-scale structures of complex materials, its reliable and accurate application to multi-component glass systems faces challenges due to limited force fields (FFs) and the complexity of chemical environments. This study demonstrates the feasibility of efficient and accurate large-scale density functional theory (DFT) calculations for multi-component glass systems. The evaluation of classical FFs based on the results of large-scale DFT calculations reveals low accuracy for non-bridging oxygen atoms, and differences in Si-O-Si angle distribution and electronic structure for X = Mg.

Summary: In this study, vanadium oxide xerogel samples were successfully synthesized through a liquid phase reaction and the interaction of films with water. The samples were thoroughly analyzed using X-ray diffraction and Raman spectroscopy, revealing the existence of two distinct phases. It was also discovered that previous misinterpretations regarding the high-pressure polymorph structure were due to the formation of a high-temperature phase. These findings highlight the potential for further refining and expanding the current structural models of vanadium oxide xerogel in future research efforts.
