“…This improves the quantum yield for electron-hole recombination, which is lowered in amount [4]. TiO 2 thin films, which are wide-bandgap semiconductors, have a notable refractive index and show high transparency, high photosensitivity, and minimal absorption in the visible wavelength range and NIR, respectively [5][6][7].…”

In this work, spectroscopic ellipsometry was used to study the optical and electrical properties of TiO2 and SiO2 thin films deposited by spin-coating at different coating rotation speeds and annealed at various temperatures. In addition, Ag thin films of different thicknesses were deposited by DC magnetron sputtering at ambient temperature. In this method, the optical band gap for TiO2 thin films is between 2.4-3.25 eV, and for SiO2 thin films, it is between 3.2-3.6 eV.The optical properties, including reflectance, transmittance, and absorbance, of TiO2, SiO2, and Ag thin films in the form of single and multilayer thin films in the wavelength range of 200-2500 nm, were investigated using an ultraviolet-visible-near infrared (UV-Vis-NIR) dual-beam spectrophotometer. In the TiO2/Ag/SiO2 multilayer thin film, the rejection was 58.6% -73.6% in the NIR wavelength range (800-2500 nm), and a transmittance of 40%-45% was achieved in the visible light range (400-700 nm).

“…Transparent conducting oxides (TCOs), namely SnO 2 , ITO, doped ZnO, etc., are widely investigated in order to be applied as electrodes in a variety of optoelectronic devices such as solar cells and light-emitting diodes [1]. Among transparent electrodes, metal oxide/metal/metal oxide (OMO) structures can achieve improved optical and electrical performances comparable to single TCO layers and very thin metallic films [2]. The development of ITO-alternative low-cost, earth-abundant, and mechanically stable TCOs exhibiting excellent transparency and electrical properties is very important.…”

ZnO/Ag/ZnO nanolaminate structures were deposited by consecutive RF sputtering at room temperature.The optical transparency, sheet resistance, and figure of merit are determined in relation to the deposition time of Ag and to the film thickness of the ZnO top layer. An improved transmittance has been found in the visible spectral range of the ZnO/Ag/ZnO structure compared to ZnO multilayers without Ag. High transmittance of 98% at 550 nm, sheet resistance of 8 Ω/sq, and figure of merit (FOM) of 111.01 × 10−3 Ω−1are achieved for an optimized ZnO/Ag/ZnO nanolaminate structure. It is suggested that the good optical and electrical properties are due to the deposition of the discontinuous Ag layer. The electrical metallic type conductivity is caused by planar located silver metal granules. The deposition of a discrete layer of Ag nano-granules is confirmed by atomic force microscopy (AFM) and cross-section high-resolution transmission electron microscopy (HRTEM) observations.
