Summary: Transparent conductive oxide (TCO) thin films, such as indium-tin oxide (ITO), are widely used in micro- and optoelectronics, with dynamic hot-probe measurement system being one method to extract the main parameters of the films. This method, demonstrated on commercial ITO films and ZnO:Al layers, can also be applied to other wide-bandgap semiconductors.

Summary: F, Mg and Ga co-doped ZnO (FMGZO) films were deposited on glass substrates at room temperature using magnetron sputtering. The effects of RF sputtering power on the structure, morphology, composition, electrical and optical properties of the films were investigated. The results showed that the FMGZO film deposited at an RF sputtering power of 15 W exhibited excellent electrical and optical performance, surpassing previously reported co-doped ZnO films.

Summary: Silicon nitride-based electrodes (SiNx) have been proposed as candidates for high-capacity transparent anode electrodes, but their low electrical conductivity limits their application in thin film batteries. To overcome this, we introduced uniformly dispersed Ag nanoparticles in SiNx thin film to enhance electrochemical properties without affecting transmittance. The addition of Ag increased the capacity of the thin-film battery and allowed for higher C rates, while maintaining optical transmittance over 60% in the visible range.

Summary: RF-magnetron sputtering was used to deposit VZO nanostructured thin films on flexible PEN substrates at room temperature. The thin films with 2% vanadium content showed the lowest resistivity and a Hall mobility of 10.62 cm(2) V-1 s(-1). These nanostructured thin films exhibit over 70% transmission in the visible region and have potential applications in electronic and optoelectronic devices.

Summary: This study investigates the interplay between energetic bombardment effects in magnetron sputtering and defect generation in two-dimensional materials using deposition of gold layers on single-layer graphene as a model system. The results suggest that controlling the energy of backscattered argon atoms can reduce material damage and enable the fabrication of multifunctional metal contacts in devices based on 2D materials.

Summary: High entropy alloys (HEAs) are advanced materials with excellent properties, and the fabrication of high entropy oxide (HEO) thin films using radio frequency (RF) reactive magnetron sputtering from a custom-made target with different oxygen flow fractions showed improvements in phase transformation, grain size, and surface roughness. Increasing oxygen flow fraction led to higher oxygen concentration and water contact angle, with the film deposited at the highest oxygen flow fraction of 50% exhibiting the highest values.

Summary: This paper analyzed the properties of tungsten oxide thin films prepared using the magnetron sputtering method. Changes in the Ar:O-2 gas mixture ratios were found to influence the structural, optical, and electrical properties of the deposited coatings significantly. The results suggest that controlling the gas atmosphere during sputtering can tailor the optoelectronic properties of tungsten oxide thin films, offering potential applications in transparent electronics.

Summary: X-ray photoelectron spectroscopy was used to investigate the direct synthesis of strontium and molybdenum oxide thin films by multitarget reactive magnetron sputtering. By varying the power applied to the Mo target, films with different concentrations of Mo atoms were produced. The XPS spectra revealed that both molybdenum and strontium were in the oxidized state, with Mo bonds in a lower valence state and similar Sr spectra for all samples.

Summary: Aluminium doped with zinc oxide (98 wt %) (AZO) thin films were fabricated on glass substrates using pulsed laser deposition (PLD) technique, showing nanoscale structures and morphology. The deposition was performed at chosen substrate temperatures and low partial pressure. A laser energy density of 4 J/cm2 was utilized, which effectively ablated the bulk AZO and minimized droplets arrival on the substrates. The AZO films exhibited crystallite sizes ranging from 31.1 to 45.4 nm, and the lowest resistivity was achieved at 6.8 x 10-5 ohm cm with an average optical transmittance of 83% in the UV-vis-NIR region. The PLD technique provides a significant avenue for crack-free and reliable thin film growth with improved electrical and optical properties.

Summary: Reactive sputtering of permalloy typically reduces crystallite size in films at low concentrations of reactive gas, improving magnetic properties. However, high oxygen concentration leads to oxidation in supermalloy, affecting parameters such as coercivity and resistivity. The balance between grain size, surface structure, disordering of atomic structure, and internal stresses determines the evolution of magnetic properties with increasing oxygen concentration.

Summary: In this study, N-type and P-type BiTe-based thin films were deposited on silicon, glass, and Kapton HN polyimide foil using magnetron sputtering technique. The morphology, microstructure, and phase constituents of the thin films were characterized by SEM/EDX, XRD, and TEM. The electrical conductivity, thermal conductivity, and Seebeck coefficient were measured by an advanced in-plane test system. The power output (open-circuit voltage and electric current) of the thin films was measured at different temperature gradients using a custom-built apparatus. The impact of deposition parameters and the dimensions of the thin films on the power output were investigated to optimize the thin-film flexible TE device for thermal energy harvesting.

Summary: In this study, Ta-doped SnO2 thin films were fabricated via a low-cost sol-gel spin coating method, achieving high electrical conductivity and high optical transparency. The optical bandgaps of the films increased due to Ta doping, however, a bandgap shrinkage was also observed due to many-body interactions. These films exhibit both transparency and conductivity, providing a new platform for optoelectronic and solar cell applications.
