“…Hence it is an important material for different applications in devices such as gas sensors [2], biosensors [3], transducers [4], solar cells [5–7], electronic and optoelectronic instruments (i.e., ultraviolet photo-detectors) [8], surface acoustic wave (SAW) gadgets [9], and transparent electrodes [10]. ZnO crystals with a grain size in the range of 1–50 nm have demonstrated optical properties, such as an UV shift of the absorption edge and strong photoluminescence at room temperature caused by quantum confinement [11] and, an improvement of the photovoltaic and sensor performance due to a high surface area [12–13]. ZnO nanostructures are obtained as nanoparticles [14], nanotubes [15], nanowires [5,7], and ultrathin films [16–17].…”

SummaryA study of transmittance and photoluminescence spectra on the growth of oxygen-rich ultra-thin ZnO films prepared by atomic layer deposition is reported. The structural transition from an amorphous to a polycrystalline state is observed upon increasing the thickness. The unusual behavior of the energy gap with thickness reflected by optical properties is attributed to the improvement of the crystalline structure resulting from a decreasing concentration of point defects at the growth of grains. The spectra of UV and visible photoluminescence emissions correspond to transitions near the band-edge and defect-related transitions. Additional emissions were observed from band-tail states near the edge. A high oxygen ratio and variable optical properties could be attractive for an application of atomic layer deposition (ALD) deposited ultrathin ZnO films in optical sensors and biosensors.

“…Whenever exposed to light, the electron-poor p-type semiconductor layer of a p-n junction, such as ZTF, is attracted to the electron-rich n-type semiconductor layer. The highest optical transmittances of 93% can be found in ZnO:Al films, making them ideal for use in solar cells [62,63]. Ali et al synthesized ZnO thin film by thermal evaporation technique.…”

Thin films have become a hot topic in the field of nanotechnology. Due to their optical and electrical characteristics, thin-film semiconductor oxides are among the semiconductor oxides with the greatest range of applications. The most popular semiconductor component is zinc oxide (ZnO). ZnO, a wide bandgap semiconductor (Eg = 3.37 eV at room temperature), have been widely used in electronic, optoelectronic, and information technology device platforms. Nano-ZnO thin films have a wide range of applications due to their remarkable properties. There are several methods for developing a thin layer of the ZnO nanomaterial. Sputtering, chemical vapor deposition (CVD), molecular beam epitaxy, pulsed laser deposition (PLD), and spray pyrolysis are among these methods. Although sputtering is the most commonly used method for high-quality applications, chemical vapor deposition and spray pyrolysis are also popular due to their low cost and ease of use. This chapter provides a brief overview of the various fabrication routes, characterization techniques, and applications of ZnO thin films, allowing us to investigate the chemical, structural, optical, and electrical properties of ZnO thin films, as well as their various applications.

“…Zinc oxide (ZnO) and aluminium-doped zinc oxide (AZO) thin films are used as window layers in solar cells [1][2][3]. Sputtering (especially rf magnetron sputtering [4]) is one of the most common choices for depositing these films due to its high deposition rate and the high stability of the films.…”

The complex interplay between the influence of oxygen partial pressure and that of rf power on the structural, electrical and optical properties of rf-magnetron-sputtered aluminium-doped zinc oxide, AZO, thin films is illustrated. The dependence of film electrical resistance and interplanar spacing of film crystallites on rf power seems to be different at higher oxygen partial pressure values than at lower ones. Film preparation was performed at room temperature (without extra heating) and low pressure p = 0.5 mTorr, varying the rf power density between P = 0.57 and 2.83 W cm −2 at different relative oxygen partial pressure values. An explanation of film properties has been sought in terms of changes in the chemical properties of the films due to the bombardment of the films during film formation with negative oxygen ions.
