“…For example, how the film deposition and growing conditions affect the residual stress and C i j coefficients [5,7,12,13,61]. Furthermore, the DFT+U may be ap-plied to more complex ZnO systems to predict optical and elastic properties when defects, impurities, and interfaces are present [3,4,6,14,22,26].…”

“…Zinc oxide (ZnO) is an important semiconductor with broad applications in technological devices such as solar cells, optical filters, and gas sensors, among many others [1][2][3]. Processed as thin films and coatings, ZnO is widely studied for applications in optoelectronics [4][5][6][7]. To enhance material performance in such applications, the study of its elastic and optical properties is of paramount importance.…”

“…To enhance material performance in such applications, the study of its elastic and optical properties is of paramount importance. In this sense, in the last decade many experimental investigations have addressed the different structural and optical properties of pure and doped ZnO systems [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. As a general remark, these investigations frequently report how the material band gap energy (E g ) and its elastic moduli depend on different parameters related to the processing method.…”

In this work, ZnO coatings were produced by the spray-pyrolysis technique and characterized by scanning electron microscopy, X-ray diffraction and optical transmittance spectroscopy. The experimental results were compared to predictions obtained from electronic-structure calculations based on the Density Functional Theory plus U (DFT+U) approach. To this purpose, the 2H, 4H and 6H polytypes of ZnO were theoretically analysed, and DFT+U was assessed for the calculation of structural, electronic and optical properties of the hexagonal ZnO structures. We found that DFT+U is an effective and accurate method that combined with experimental measurements, allows a deeper insight about the coatings of the wurtzite (2H) phase synthesized in the laboratory. This comprehensive study of the pure ZnO is the first step towards the study of more complex ZnO-based coatings.

“…In particular, doping with rare earth elements found to enhance the electrical and optical properties of ZnO, which can be beneficial as a TCO [ 4 ]. In this regard, praseodymium (Pr) co-doped AZO thin film was prepared by the nebulized spray technique [ 11 ]. Again, the Al doping content was fixed at 3 wt%, while different doping concentrations of Pr were adopted.…”

“…Furthermore, in order to achieve optimal functional properties, ZnO was doped with many different elements, such as In, Ga, Al, Li, La, Mg, Sm, Pr, etc. [ 3 , 4 , 11 , 12 ]. Among them, Al- doped ZnO (AZO) exhibits the lowest resistivity (2 × 10 −4 Ω cm), which makes it as a leading candidate to replace ITO [ 13 ], and a number of reports can be found in which doped ZnO was used for optoelectronic applications [ 10 , 14 , 15 , 16 , 17 , 18 , 19 ].…”

With the continuous growth in the optoelectronic industry, the demand for novel and highly efficient materials is also growing. Specifically, the demand for the key component of several optoelectronic devices, i.e., transparent conducting oxides (TCOs), is receiving significant attention. The major reason behind this is the dependence of the current technology on only one material—indium tin oxide (ITO). Even though ITO still remains a highly efficient material, its high cost and the worldwide scarcity of indium creates an urgency for finding an alternative. In this regard, doped zinc oxide (ZnO), in particular, solution-processed aluminum doped ZnO (AZO), is emerging as a leading candidate to replace ITO due to its high abundant and exceptional physical/chemical properties. In this mini review, recent progress in the development of solution-processed AZO is presented. Beside the systematic review of the literature, the solution processable approaches used to synthesize AZO and the effect of aluminum doping content on the functional properties of AZO are also discussed. Moreover, the co-doping strategy (doping of aluminum with other elements) used to further improve the properties of AZO is also discussed and reviewed in this article.
