The semiconductor's realization is a very significant stage of optoelectronics devices. In this work, an elaboration of the TiO2 semiconductor is made with various solution flow rates via spray pyrolysis. The structural and optical properties of pure TiO2 are investigated with several characterization techniques which include: X‐ray diffraction (XRD), Raman spectroscopy, and UV–vis spectrophotometry. The XRD of elaborated TiO2 layers exhibits nanocrystalline nature with a preferential orientation at the (101), a unique phase of anatase TiO2. The apparition of vibration modes in Raman spectra confirms the TiO2 formation with a single phase. The produced TiO2 has an optical transmission varying from 90% to 70% in the visible wavelength. The energy band gaps are 3.42, 3.32, and 3.28 eV for the TiO2 elaborated at 1, 1.5, and 2 mL min−1, respectively which prove the semiconducting properties of TiO2. All other optical parameters such as refractive index (n), extinction coefficient (k), and dielectric constant (εr, εi) vary with the variation of solution flow rate. These investigations discover that the properties of TiO2 layers can be adjusted by solution flow rate. It seems that the process of spray pyrolysis provides a facile way to control the quality of TiO2 thin layers.

“…Along with functional photosensitive and modulating layers of optoelectronic devices, indium and tin oxides (ITO) are one of the key semiconductor materials in electronics, which, depending on the field of application of the developed system, can function both as transparent conductive contacts, antireflection coatings and buffer coatings [1][2][3][4][5]. ITO coatings are transparent in the visible and near infrared spectrum regions, flexible, non-toxic, and have a relatively high conductivity, which allows them to be used in photovoltaics [6][7][8][9], flexible electronics [10-13], and display technologies [14 -17].…”

The paper presents the analysis of the surface relief of ITO conductive layers structured with single-walled carbon nanotubes. The deposition of ITO films and carbon nanotubes was carried out by laser-oriented method using a CO2 laser. The optical scheme was matched to the control electric grid; the strength of the electric field was varied in the range of 100–600 Vcm–1. To analyze the surface, atomic force microscopy in the contact mode and measurement of the wetting angle by sessile drop method was used. Roughness of pure ITO was about 1.8 nm, while in laser-vacuum deposition of carbon nanotubes, roughness varied from 6.4 nm to 22.1 nm with an increase in the electric field during deposition. The relationship between roughness and surface area of coatings and the wetting angle was considered. An increase in the wetting angle from 101.8 degrees, in the case of pure ITO, to 115.0-128.6 degrees, with the deposition of carbon nanotubes, was shown. The results obtained indicate an improvement in the resistance of ITO coatings to moisture during the deposition of carbon nanotubes, which makes it possible to expand their operating conditions and scope in optical electronics, laser and display technology.
