“…A topic broadly researched for undoped ZnO thin films is their application in FETs either in the conventional top-gate and bottom-gate approaches [159], or with junction interface engineering for increased mobility [160]. The piezoelectric properties of ZnO make it interesting for piezoelectric nanogenerators [161] for energy harvesting as well as surface acoustic wave generators and filters that are applied in a variety of sensors [162] and as microfluidic micropumps [163]. Memristors utilizing ZnO films are also researched, where the ferromagnetic metallic film is often sandwiched between two ZnO films and the magnetic switching occurs through interface oxidation of the Fe by creation of oxygen vacancies in ZnO [164].…”

Zinc oxide (ZnO) is a fascinating wide band gap semiconductor material with many properties that make it widely studied in the material science, physics, chemistry, biochemistry, and solid-state electronics communities. Its transparency, possibility of bandgap engineering, the possibility to dope it into high electron concentrations, or with many transition or rare earth metals, as well as the many structures it can form, all explain the intensive interest and broad applications. This review aims to showcase ZnO as a very versatile material lending itself both to bottom-up and top-down fabrication, with a focus on the many devices it enables, based on epitaxial structures, thin films, thick films, and nanostructures, but also with a significant number of unresolved issues, such as the challenge of efficient p-type doping. The aim of this article is to provide a wide-ranging cross-section of the current state of ZnO structures and technologies, with the main development directions underlined, serving as an introduction, a reference, and an inspiration for future research.

“…[11][12][13][14] Different approaches have been used for the fabrication of PENGs on nonflexible substrate such as GaN, 15 glass, 16,17 titanium foil, 18 and silicon. [19][20][21][22] However, these materials exhibit poor flexibility and deformation due to which PENGs are facing a challenge in practical applications. In addition, there has been rapid progress on fabricating stretchable or flexible PENGs based on ZnO nanorods.…”

Textile-based piezoelectric nanogenerator generates electrical energy from human motion. Here a novel type of textile-based piezoelectric nanogenerator is reported which is fabricated using the growth of silver-doped zinc oxide on carton fabric. Along with the optical and structural characterization of silver-doped zinc oxide nanorods, the electrical characterization was also performed for silver-doped zinc oxide piezoelectric nanogenerator. The silver-doped zinc oxide piezoelectric nanogenerator was found to generate three times greater power compared to undoped zinc oxide piezoelectric nanogenerator. By applying external mechanical force of 3 kgf and 31 MΩ of load resistance, the silver-doped zinc oxide piezoelectric nanogenerator generated an output power density of 1.45 mW cm−2. The effect of load resistance and load capacitor was determined and optimum values were calculated. The maximum output power was observed at a load resistance of 31 MΩ. The silver-doped zinc oxide piezoelectric nanogenerator was utilized to charge load capacitors and found that maximum energy could be stored at optimum load capacitance of 22 nF in 600 s (1800 cycles). This research may provide the opportunity to design high-output textile-based nanogenerators for practical applications like powering portable devices and sensors.

“…The Li-doped Cu 2 O/ZnO synthesized by radio frequency magnetron sputtering was flexible and transparent. Moreover, PENGs with the ZnO TFs deposited onto a Si substrate by pulsed laser ablation at a substrate temperature of 500°C generated a voltage, current and power of 95 mV, 35 µA/cm 2 and 5.1 mW/cm², respectively (Qin et al, 2016a;2016b). The PENGs with Ga-doped ZnO NWs produced a higher voltage ranging from 120 to 560 mV (Zhao et al, 2015b) if compared with undoped ZnO NWs generated a lower voltage of up to 25 mV (Wang et al, 2008).…”

“…Meanwhile, ZnO Nanobelts (NBs) have bigger d 33 (14.3-26.7 pm/V) than that of ZnO Thin Films (TFs) synthesized by sputtering deposition (14 pm/V) (Dagdeviren et al, 2013). However, the ZnO TFs deposited onto a Si substrate by pulsed laser ablation has a high piezoelectric constant of 49.7 pm/V (Qin et al, 2016a;2016b) because it exhibited a preferred c-axis orientation. In addition, ZnO Nanorods (NRs) were reported have the d 33 ranging from 4.41 to 11.8 pm/V (Tamvakos et al, 2015) for single crystal and they further reached a highest value of 26.7 pm/V when measured for ZnO NBs (Zhao et al, 2004).…”

The ferromagnetic cobalt doped into Zinc Oxide (ZnO) crystals is a promising method for enhancing the performance of PiezoelectricBased Nano Generators (PENGs). The study reports the characterization and testing PENGs which simply fabricated from cobalt-doped ZnO nanofibers (NFs) synthesized by electro spinning machine. The electro spinning processes were conducted at a flow rate of 4 µL/min and at various cobalt concentrations followed by sintering at a temperature of 500°C. The X-Ray Diffraction (XRD) spectra demonstrate that the crystalline diameter of Co-doped ZnO NFs increased as the content of cobalt increased, up to a concentration of 9%. Meanwhile, the maximum output voltage and power density of PENGs with Co-doped ZnO NFs were 221.6 mV and 148.8 nW/cm 2 , respectively when the PENGs were subjected to a cyclic mechanical load of 0.5 kg. Therefore, PENGs fabricated from Co-doped ZnO NFs are challenging for the next generation of self-powered devices.
