“…At the same time, the nonmonotonic nature of the change in the optical gap for the ZnO-Me 2 O 3 system (Me = Al, Sc, Y and In), depending on the content of impurity oxide to the host ZnO, was observed by other authors [27,31]. The observed band gap narrowing in the ZIO films deposited from targets with In 2 O 3 content above 2.5 mol% is associated with the formation of a band tail in the band gap with an increase in the carrier concentration [31,32], or, conversely, due to a possible decrease in the carrier concentration related with a high probability of the formation of charged acceptor complexes (V 2− Zn -In + Zn ) [33]. In confirmation of the above, as shown by measurements of electrical characteristics, the surface resistance R S decreases with an increase in the content of In 2 O 3 to 5.0 mol%, and then slightly increases at 10 mol% (Figure 3b).…”

The development of optoelectronic devices based on flexible organic substrates substantially decreases the possible process temperatures during all stages of device manufacturing. This makes it urgent to search for new transparent conducting oxide (TCO) materials, cheaper than traditional indium-tin oxide (ITO), for the low-temperature deposition of transparent electrodes, a necessary component of most optoelectronic devices. The article presents the results of a vertically integrated study aimed at the low-temperature production of TCO thin films based on a zinc-indium oxide (ZIO) system with acceptable functional characteristics. First, dense and conducting ceramic targets based on the (100-x) mol% (ZnO) + x mol% (In2O3) system (x = 0.5, 1.5, 2.5, 5.0, and 10.0) were synthesized by the spark plasma sintering method. The dependences of the microstructure and phase composition of the ZIO ceramic targets on the In2O3 content have been studied by powder X-ray diffraction, scanning electron microscopy and energy dispersive X-ray spectroscopy methods. Then, a set of ZIO thin films with different Zn/In ratios were obtained on unheated glass substrates by direct current (dc) magnetron sputtering of the sintered targets. Complex studies of microstructure, electrical and optical properties of the deposited films have revealed the presence of an optimal doping level (5 mol% In2O3) of the ZIO target at which the deposited TCO films, in terms of the combination of their electrical and optical properties, become comparable to the widely used expensive ITO.

“…Even if the thickness of b‐CNF substrates is increased to 50 µm, the optical transmittance is still over 80% in the wavelength range between 400 and 800 nm. In addition, transparent conductive indium zinc oxide (IZO) as the electrode is sputtered onto the b‐CNF substrate with the thickness of 9 µm . With increasing thickness of the transparent conductive oxide film, the light transmittance and the conductivity declines and improves, respectively.…”

devices, flexible substrates play a key role to fabricate high-performance electronics. In the past decade, various flexible substrates have been greatly developed. For instance, Chongwu and co-workers fabricated silver nanowire films on flexible polyethylene terephthalate (PET) substrates with good mechanical flexibility and demonstrated the application in a touch panel. [7] Johansson and co-workers reported a polyethylene naphthalate (PEN) substrate coated by Ag nanowire network for an extremely lightweight and ultraflexible colloidal quantum dots solar cell. [8] Jeong and co-workers fabricated copper conductors on polyimide and polyethersulfone substrates, exhibiting the potential accessibility for flexible electronics. [9] The abovementioned flexible substrates exhibit excellent stretchable ability and high-flexible performance. Because of their excellent mechanical and chemical stability, it takes extremely long time for them to degrade or decompose in the nature, leading to environmental pollution. Therefore, more and more attention is paid to looking for flexi ble, biocompatible, and environmentally friendly biomass substrates for wearable devices. [6,[10][11][12][13] Flexible biomass substrates based on nanofibrillated cellulose have been explored and are expected to be used in wearable electronics due to their excellent mechanical properties, renewability, and raw material abundance. Ma and co-workers successfully fabricated gallium arsenide microwave devices on flexible wood-derived cellulose nanofibril paper. [14] Ju and co-workers reported flexible, transparent phototransistors on biodegradable wood-derived cellulose nanofibrillated fiber substrates toward environment friendly electronics. [15] Hu and co-workers fabricated flexible organic field-effect transistors on tailorable softwood-derived nanopapers. [16] These successful studies suggest the feasibility to fabricate environment friendly cellulose-based substrates for flexible electronics, and further accelerate development of the flexible wearable devices.Currently flexible perovskite solar cells (PSCs) have gained wide attention by their excellent performance and potential application in wearable energy devices. [13,[17][18][19] As is well known, high performance flexible perovskite devices are still based on nonbiocompatible and nondegradable plastic substrates such as PET, PEN, and polydimethylsiloxane. Yu and co-workers first reported flexible perovskite solar cells fabricated on Wearable devices are mainly based on plastic substrates, such as polyethylene terephthalate and polyethylene naphthalate, which causes environmental pollution after use due to the long decomposition periods. This work reports on the fabrication of a biodegradable and biocompatible transparent conductive electrode derived from bamboo for flexible perovskite solar cells. The conductive bioelectrode exhibits extremely flexible and light-weight properties. After bending 3000 times at a 4 mm curvature radius or even undergoing a crumpling test, it still shows excellent e...

“…In this case, larger grains will be expected because hosted atoms with larger size replace the Zn atoms in the lattice. Additionally, some researchers mentioned that the morphology of the samples varies because of particle agglomeration due to indium content and therefore bigger particles were obtained [32,35,36,39,52].…”

This study aims to examine the studies regarding In doped ZnO published in the Web of Science database. A total of 777 articles were reached (31 March 2020). The articles were downloaded for the bibliometric analysis and collected in a file. The file was uploaded to VOSViewer programme in order to reveal the most used keywords, words in the abstracts, citation analyses, co-citation and co-authorship and countries analyses of the articles. The results showed that the most used keywords were “ZnO”, “photoluminescence”, “optical properties”, “thin films” and “doping”. These results indicate that the articles mostly focus on some characteristics of In doped ZnO thin films such as structural, optical and electrical features. When the distribution of the number of articles using the keywords by year was searched, it was found that recent articles focus mainly on synthesis of In doped ZnO film via chemical routes such as sol-gel and hydrothermal syntheses, and on ZnO-based device applications such as solar cells and gas sensors. The most used keywords were also found to be films, X-ray, glass substrate, X-ray Diffraction (XRD), spectra and layer. These results indicate that the studies mostly focus on In doped ZnO thin films as transparent conductive oxide (TCO) material used in device applications like solar cells. In this context, it was found that structural, topographical, optical, electrical and magnetic properties of In doped ZnO films were characterized in terms of defected structure or defect type, substrate temperature, film thickness and In doping content. When the distribution of these words is shown on a year-by-year basis, it is evident that more recent articles tend to focus both on efficiency and performance of In doped ZnO films as TCO in solar cells, diodes and photoluminescence applications both on nanostructures, such as nanoparticles, and nanorods for gas sensor applications. The results also indicated that Maldonado and Asomoza were the most cited authors in this field. In addition, Major, Minami and Ozgur were the most cited (co-citation) authors in this field. The most cited journals were found to be Thin Solid Films, Journal of Materials Science Materials in Electronics and Journal of Applied Physics and, more recently, Energy, Ceramics International, Applied Physics-A, Optik, Material Research Express, ACS Applied Materials and Interfaces and Optical Materials. The most co-cited journals were Applied Physics Letters, Thin Solid Films, Journal of Applied Physics, Physical Review B, and Applied Surface Science. Lastly, the countries with the highest number of documents were China, India, South Korea, USA and Japan. Consequently, it is suggested that future research needs to focus more on synthesis and characterization with different growth techniques which make In doped ZnO suitable for device applications, such as solar cells and diodes. In this context, this study may provide valuable information to researchers for future studies on the topic.
