“…In paper [32], by adding the CuO nanoparticles with a concentration of 3-7 wt.%, the optical transmittance was increased; however, the electrical conductivity was decreased by an order of magnitude. In the case of ITO/CeO 2 structures [33], under a concentration of 0.5-2.0 wt.% of CeO 2 , the electrical resistance drops from 2.27 × 10 −4 Ω × cm to 1.87 × 10 −4 Ω × cm and the optical band gap shifts from 3.58 eV to 3.65 eV. A noticeable decrease in the resistivity (1.5-2 times) is observed when Zn is used as a doping material [34].…”

In many electro-optical devices, the conductive layer is an important key functional element. Among others, unique indium tin oxide (ITO) contacts take priority. ITO structure is widely used as the optical transparent and electrically conductive material in general optoelectronics, biosensors and electrochemistry. ITO is one of the key elements in the liquid crystal (LC) displays, spatial light modulators (SLMs) and LC convertors. It should be mentioned that not only the morphology of this layer structure but also the surface features play an important role in the study of the physical parameters of the ITO. In order to switch the surface properties (roughness, average tilt angle and surface free energy) of the ITO via the laser-oriented deposition (LOD) method, carbon nanotubes (CNTs) were implanted. In the LOD technique, the CO2 laser (λ = 10.6 μm, P = 30 W) with the control electric grid was used. The switching of the deposition conditions was provided via the varying electrical strength of the control grid in the range of 100–600 V/cm. The diagnostics of the surfaces were performed using AFM analysis and wetting angle measurements. The components of the surface free energy (SFE) were calculated using the OWRK method. The main experimental results are as follows: the roughness increases with a rise in the electric field strength during the deposition of the CNTs; the carbon nanotubes provide a higher level of the dispersive component of SFE (25.0–31.4 mJ/m2 against 22.2 mJ/m2 in the case of pure ITO); the CNTs allow an increase in the wetting angle of the 5CB liquid crystal drops from 38.35° to 58.95°. Due to the possibility of the switching properties of the ITO/CNT surfaces, these modifications have potential interest in microfluidics applications and are useful for the liquid crystal’s electro-optics.

“…Chiang et al [8] obtained the resistance of 350-500 Ω/sq, resistivity of ~10 Ω and light transmittance of 88% in the visible range of ITO films by managing the magnetron sputtering parameters. The doping of the ITO films with metals was also used to improve the electrical and optical properties [9,20]. Y.T.…”

“…Li et al [9] found that Zr-doped ITO films demonstrated higher transmittance values compared to undoped ones. The addition of low concentration (up to 2 wt.%) cerium reduced the surface roughness, increased the density, transparency and electrical conductivity of the ITO films [20].…”

The plasma-activated reactive evaporation technique was used for the formation of indium-tin-oxide (ITO) films. The ITO films were deposited on a heated (up to 350 °C) glass substrates using various mass ratios of indium and tin. The optical and electrical properties of the deposited ITO films were determined. The influence of the indium-to-tin mass ratio on the optical transmittance, bandgap, resistivity and resistance of ITO films was investigated. The bandgap of ITO films was increased from 3.18 to 3.37 eV, and the MIn/MSn ratio increased from 4.25 to 10.00. The average values of optical transmittance at the visible light wavelengths increased from ~43% to ~64% as tin mass was reduced. We demonstrated that ITO films with low resistivity ranging from 7.4 × 10−3 to 43.7 × 10−3 Ω·cm were obtained, and the MIn/MSn ratio changed from 4.25 to 10.00. The ITO film formed at the 9.25 MIn/MSn ratio demonstrated high transparency, a wide bandgap and optimal resistivity and resistance values. The heating characteristics indicated that the frozen ice on the ITO films was completely removed after 30 s when the applied voltage was 24 V.
