“…This is a good indicator, showing that better crystal quality can be obtained using air bubbles in the CBD method. The higher aspect ratio can be regarded as a key factor for determining the energy-conversion efficiency of solar cells [ 24 , 25 ]. The growth rates versus times are revealed in Figure 5 d. For both methods, the growth rate was increased with growth times.…”

Ultraviolet (UV) photodetectors (PDs) based on high-quality well-aligned ZnO nanorods (NRs) were fabricated using both modified and conventional chemical bath deposition (CBD) methods. The modified chemical bath deposition (M-CBD) method was made by adding air bubbles to the growth solution during the CBD process. The viability and effectiveness of M-CBD were examined by developing UV PDs based on ZnO NRs. The ZnO nano-seed layer was coated on a glass substrate utilizing radiofrequency (RF) sputtering. The impact of the different growth-times on morphology, growth rate, crystal structure, and optical and chemical properties were investigated systematically using different characterization techniques, such as field-emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD) analysis, UV–VIS double beam spectrometer, and energy dispersive X-ray analysis (EDX), respectively. The Al/ZnO UV PDs based on ZnO nanorods were fabricated with optimum growth conditions through the two methods of preparation. This study showed that the synthesized ZnO NRs using the M-CBD method for different growth times possess better properties than the conventional method under similar deposition conditions. Despite having the highest aspect ratio and growth rate of ZnO NRs, which were found at 4 h growth duration for both methods, the aspect ratio of ZnO NRs using the M-CBD technique was comparatively higher than the conventional CBD method. Besides, the UV PDs fabricated by the M-CBD method at 5 V bias voltage showed high sensitivity, short response time, quick recovery time, high gain, low dark current, and high photocurrent compared with the UV PD device fabricated by the conventional CBD method.

“…-Hydrothermal synthesis: Zinc acetate dihydrate is dissolved in 250 ml of distilled water; 0.3 ml of ammonium hydroxide is then added to this solution and stirred at room temperature for 30 minutes. The steel substrate with the seed that was prepared previously by the same sol-gel method is placed vertically in this aqueous solution for 1 hour at 90 o C. More details of the growth conditions can be found in the article by Wided Chebil et al [2].…”

This paper presents a simple process of fabricating a superhydrophobic carbon steel surface with high water repellence and good corrosion resistance. The steel surface was covered by thin ZnO layers via various methods of sol-gel method, hydrothermal synthesis, and electrochemical deposition, then further functionalised with methyltrichlorosilane. Morphological features observed by a scanning electron microscope (SEM) show that ZnO layers are composed of micro/nanostructures. Furthermore, the chemical composition of these films has been analysed by an energy dispersive X-ray spectroscopy (EDX). An optimum experimental condition, based on the type of Zn deposition method, has been obtained to provide superhydrophobic properties with a water contact angle of 152 ± 2o. In a 3.5 wt% NaCl solution, the corrosion resistance properties of the superhydrophobic ZnO-coated steel are found to be very good with an anti-corrosion efficiency of 93.12%.

“…Such modifications intend to improve and/or better control specific parameters and reactions to promote enhanced conditions for the resulting thin films. Different strategies such as microwaves [51][52][53][54][55][56][57][58][59][60][61][62][63][64], hydrothermal [65,66], light [67,68], seed-layer [69,70], ultrasonic wave [71], and surfactants [72] have been reported as additional/ alternative conditions for the CBD. Some advantages that such strategies have offered are time reduction [51,54,60], energy saving [64,67] and enhanced physical properties for the further applications [66,69,72].…”

The material deposition in aqueous solution, also known as chemical bath deposition (CBD), is a well-established technique for the fabrication of semiconducting thin films. The success of the CBD technique is mainly based on the relatively easy implementation and operation requirements. The CBD has importantly contributed to the development of sensors, optical devices and solar cells applications. In this review, the origins and current state of the art of the CBD technique, the involved physicochemical processes, the growing mechanisms, and the analytical techniques for the estimation of optimal physicochemical conditions for the film deposition are discussed. Emphasis on authors' experience on CBD of CdS, ZnS, Zn (OH) 2 , and ZnO films are here highlighted, following methodologies for a high control of the deposited materials, such as the species distribution diagrams and the solubility curves.
