Summary: Si-doped beta-Ga2O3 thin films grown on vicinal a-Al2O3 (0001) substrates exhibit high electrical conductivity and deep ultraviolet (DUV) transparency, making them promising candidates for transparent electrodes. The use of miscut Al2O3 substrates promotes improved crystal quality and electrical properties. The Si-doped films achieved a high conductivity of 37 S cm(-1) and average DUV transparency of 85% on a 6 degrees miscut substrate. The films also exhibit low work function, making them suitable for efficient electron injection in DUV optoelectronic devices.

Summary: LDHs are a type of cationic-layered solid that can be synthesized for various advanced functions, and in this work, an in-situ and patternable thin film synthesis of interconnected Zn-Cr LDH particles was successfully demonstrated at room temperature within minutes. The replacement of interlayer anion with perfluorooctanoate results in an increased interlayer sheet distance and the formation of a super-hydrophobic thin film capable of adsolubilizing and retaining organic guest molecules.

Summary: Transparent metallic films (TMFs) are the best candidates among transparent conductive films (TCFs) due to their ability to maintain high electrical conductivity and optical transparency simultaneously under mechanical deformation. Empirical relationships and a figure-of-merit expression have been proposed to predict the overall quality and performance of TMFs, particularly in silver nanohole array TMFs. The experimental data and theoretical predictions show that a beta value of 5 is better for characterizing the performance of nanohole array TMFs compared to beta value of 10 for TCFs.

Summary: Over the past few decades, the research on electrochromism has focused on altering the optical transmittance of electrochromic (EC) materials using a small applied voltage. Tungsten oxide (WO3) is commonly used in EC devices (ECDs) to achieve this effect. In this study, WO3 films were produced using a sol-gel spin-coating method, and the influence of various transparent conducting oxides (TCOs) on the construction of ECDs was investigated. The combination of fluorine-doped tin oxide (FTO) and indium-doped tin oxide (ITO) as the TCO and counter electrode, respectively, exhibited the highest coloration efficiency.

Summary: It is possible to fabricate indium zinc oxide (IZO) films with a wide range of optoelectronic properties by using different oxygen contents in the working gas during sputtering deposition. Additionally, high deposition temperature is not necessary to achieve excellent transparent electrode quality in the IZO films. By modulating the oxygen content in the working gas during RF sputtering, IZO-based multilayers were deposited, consisting of ultrathin IZO unit layers with high electron mobility alternating with layers characterized by high concentration of free electrons. Through optimizing the thicknesses of each unit layer, low-temperature 400 nm thick IZO multilayers with excellent transparent electrode quality were obtained, exhibiting low sheet resistance, high transmittance in the visible range, and a very flat multilayer surface.

Summary: It was found that using a precursor solution with a lower metal cation concentration can lead to BLSO thin films with denser microstructures, lower resistivity, higher optical transmittance, and good thermal stability. The highest room-temperature carrier mobility of 53 cm(2) V-1 s(-1) was achieved among all solution-processed donor-doped BaSnO3 thin films. The proposed microstructural engineering offers a sensible and feasible avenue to optimize the optoelectronic performance of transparent conducting thin films.

Summary: This study investigates the chemical stability of SrVO3 (SVO), a potential replacement for conventional ITO in the new generation of TCO materials. By subjecting the SVO thin films to heat treatments in the range of 150-250 degrees Celsius, the researchers are able to accelerate the natural aging process and observe changes in the structural, electrical, and optical properties. The results indicate surface oxidation at low annealing temperatures and the destruction of the perovskite phase at temperatures above 200 degrees Celsius. The goal of this study is to understand the thermal degradation and long-term stability issues of vanadate-based TCOs and identify technologically viable solutions for their application.
