“…The optical detectors are one of the most important components in wearable electronic devices for measuring light in various applications [1]. Semiconductor materials with wide-bandgap such as ZnO, SiC, GaN, and TiO2 have been used for producing Ultraviolet (UV) PDs and solar cells [2][3][4][5][6][7][8][9][10]. Among them, ZnO has attracted researchers' attention due to its unique features, including cheapness, high chemical stability, strong radiation hardness, high charge carrier mobility, and most importantly, the 3.37 eV wide-bandgap [3,6,[11][12][13][14].…”

Three metal-semiconductor-metal (MSM) ultraviolet flexible self-powered photodiode (PDs) were fabricated, which differed in the shape of the electrodes. Here, the effect of the electrode's shape on the height of the Schottky barrier and the electric field in these PDs was investigated. They were prepared based on porous Zinc Oxide (ZnO) on fiberglass. Different shapes of the electrodes affect the height of the Schottky barrier in each metal-semiconductor contact and provide the basis for the formation of self-powered PDs. It also affects the electric field generated in the PD's bias condition and affects the PD's parameter. They were fabricated using the radio frequency (RF) sputtering technique, and copper electrodes with different shapes and a sample with interdigitated electrodes were created using the printed circuit board (PCB) method. The photocurrent of the sample with circular and rectangular electrodes was equal to 470 μA in 15V bias, which was twice as good as a sample with an interdigitated MSM structure. It also had the best photocurrent at 0V, which is equal to 0.8 μA. This sample had the best response time among these three samples, which was equal to 440 ms. It is noteworthy that the simulation data confirmed the practical results.

“…However, ZnO nanoparticles are having a very low efficiency for the separation of electron hole pairs due to fast recombination of charge carriers [10]; therefore, efforts have been made to suppression of the recombination of photogenerated electron-hole pairs in ZnO nanoparticles. In this regard, ZnO nanoparticles have been doped or conjugated with other nanoparticles such as ZnO/CdTe for antimicrobial applications [11], ZnO/CdSe for photoelectrode for splitting water [12], ZnO/CdS for enhanced field emission behavior [13], ZnO/CdS for enhanced photocatalytic activity [14], ZnO/CdS for antibacterial activity [15], ZnO/CdS for enhanced photocatalytic H 2 evolution [16], and ZnO/CdS nanocomposite for Solar cell [17]. Herein, we have attempted to enhance the photocatalytic efficiency ZnO nanoparticles by synthesizing a composite with CdS nanoparticles, and further evaluated its antimicrobial and antibiofilm.…”

Microbial infectious are becoming a global threat, which is a reason for rise in mortality of human beings. One of the reasons for this mortality has been the drug resistance in microbes. The drug resistance poses a major challenge for effective control of microbial infections, and this threat has prompted us to search for alternative strategy to control the microbial infections. Recently, nanomaterials have emerged as an alternative to conventional platforms because they combine multiple mechanisms of action into one platform due to the distinctive properties of nanosized materials. In the present research we have attempted to synthesize ZnO/CdS nanocomposite for its application as an antimicrobial agent. We have characterized the synthesized nanocomposites by X-ray diffraction (XRD), ultraviolet-visible spectroscopy (UV-Vis), photoluminescence spectroscopy (PL), field emission scanning electron microscopy (FESEM) and high-resolution transmission electron microscopy (HRTEM). The nanocomposites have exhibited good antibacterial property against Gram positive and Gram-negative organisms by virtue of the generation of reactive oxygen species (ROS) inside the cells, as reflected by ruptured appearances in the FESEM micrographs. Apart from antimicrobial activity, it also inhibited biofilm formations in Pseudomonas aeruginosa, a causative organism in lung infection and burn associated infections.
