“…In this case, quasi-one-dimensional materials usually have a larger surface area compared to 2D structures, which can affect their chemical activity and interaction with the environment [17]. In addition, the semiconducting properties of copper oxide allow its use in solar cells, showing high efficiency in converting solar energy into electrical energy [18]. Zinc oxide is also widely used in electronics, sensorics, and other technologies [19].…”

The most effective methods for the synthesis of nanostructured copper and zinc oxides, which have unique properties and potential applications in a variety of fields including electronics, photonics, sensorics, and energy conversion, are analyzed. Special attention is paid to laser-based methods for synthesizing oxide nanostructures, with an emphasis on the importance of controlling power density distribution to influence the quality and properties of the nanomaterials. The great significance of wavefront shaping techniques for controlling laser-initiated processes is highlighted, which enable precise control over the phase and amplitude of light waves to achieve desired outcomes in optics and laser-assisted formation of one- and two-dimensional structures of oxide semiconductor materials. Diffractive computer optics is presented as a powerful tool for precise beam control. The significance of laser-induced thermochemical processes for creating and improving the properties of ZnO and CuO-based nanomaterials is discussed. The presented analysis shows that the synthesis of nanocomposites based on ZnO and CuO using pulse-periodic laser treatment, coupled with precise laser beam control using free-form diffractive optics, presents novel opportunities for applications in optoelectronics, sensor technology, electronics and portable energy sources manufacturing, and various other fields.

“…[ 1–3 ] Transparent and conductive films are mainly used in various displays for their transparency and conductivity. [ 4–7 ] Indium tin oxide (ITO) film (Sn‐doped In 2 O 3 , referred to as ITO) has a higher electron concentration (10 21 cm –1 ), higher electron mobility (15–45 cm 2 V –1 s –1 ), a wider prohibition, an n‐type semiconductor material with a bandwidth (3.65 eV), which has high infrared reflectance and high ultraviolet absorption, high electrical conductivity, high visible light transmittance, strong mechanical hardness, and good chemical stability. [ 8–11 ] Liquid crystal displays (LCD), plasma displays (PDP), photoluminescent displays (EL/OLED), touch panels, and solar cells are the most widely used transparent conductive film materials for different electronic instruments.…”

In this study, magnetron sputtering is implemented to adjust the sputtering power from 156 to 306 W at room temperature, and thin film samples of indium tin oxide (ITO) on a flexible fluorphlogopite substrate are taken. With the increase in power, the resistivity of the film first decreases and then increases. The resistivity is at least 1.51 × 10–3 Ω cm at 276 W, and the highest resistivity is 2.93 × 10–2 Ω cm at 156 W. The average light transmittance of the film (400–800 nm) decreases with the increase in power within the range of 156–276 W, The highest average transmittance is 92.6% at 156 W. The quality factor of the film first rises and then decreases as the power increases, it is as high as 4.47 × 10–3 Ω–1sq at 276 W. All the AFMs show that the roughness of the sample does not significantly change with power. The SEM picture shows that as the power increases from 156 to 276 W, the grain size increases slightly. All samples are bent 1200 times around a steel cylinder, and the sheet resistance does not change more than 5%.

Self-assembly is the most promising low-cost and high-throughput methodology for nanofabrication. This paper reports the optimization of a self-assembly process at room temperature for the growth of copper oxide (CuO) based nanostructures over a copper substrate using aqueous potassium hydroxide (KOH) solution as the oxidizing agent. The monoclinic phase of CuO nanostructures grown over the copper substrate was confirmed from the X-ray diffraction (XRD) and micro-Raman analysis. The overall chemical composition of nanostructures was confirmed to be that of CuO from its oxidation state using X-ray photoelectron spectroscopy (XPS). Photodetectors were engineered with the structure Cu/CuO/Ag. The photodetectors exhibited a response to both ultraviolet and visible light illumination. The optimized Cu/CuO/Ag structure exhibits a responsivity of ~ 1.65 µA/W, with an ON:OFF ratio of ~ 69 under a bias voltage of 0.01 V. The temporal dependence of photo-response for the optimized photodetector displayed the persistent nature of photoconduction indicating a delay in charge carrier recombination which could potentially be exploited for photovoltaic applications.
