“…To maintain a stable structure, the polar surfaces generally have facets or exhibit massive surface reconstructions, but ZnO ± (0001) surfaces are exceptions: they are atomically flat, stable and exhibit no reconstruction [1,2]. Efforts to understand the superior stability of the ZnO ± (0001) polar surfaces are at the forefront of research in today's surface physics [3][4][5][6]. The other two most commonly observed facets for ZnO are {2110} and {0110}, which are non-polar and have lower energy than the {0001} facets.…”

“…ZnO is transparent to visible light and its conductivity can be increased through doping. ZnO nanostructures have a wide range of high technology applications like surface acoustic wave filters [1], photonic crystals [2], photodetectors [3], light emitting diodes [4], photodiodes [5], gas sensors [6], optical modulator waveguides [7], solar cells [8,9] and varistors [10]. ZnO is also receiving a lot of attention because of its antibacterial property and its bactericidal efficacy has been reported to increase as the particle size decreases [11].…”

One-dimensional nanostructures exhibit interesting electronic and optical properties due to their low dimensionality leading to quantum confinement effects. ZnO has received lot of attention as a nanostructured material because of unique properties rendering it suitable for various applications. Amongst the different methods of synthesis of ZnO nanostructures, the hydrothermal method is attractive for its simplicity and environment friendly conditions. This review summarizes the conditions leading to the growth of different ZnO nanostructures using hydrothermal technique. Doping of ZnO nanostructures through hydrothermal method are also highlighted.

“…The research has led to the development of numerous ZnO thin film and nanowire based devices ranging from surface acoustic wave filters [1], photonic crystals [2], light emitting diodes [3], photodetectros [4], photodiodes [5], gas sensors [6] and solar cells [7], to name a few. This is due to the unique properties of ZnO including a wide bandgap (3.37 eV) as well as specific electrical and optoelectrical properties of the II-VI semiconductor group [2][3][4].…”

Zinc oxide (ZnO) nanowires were synthesised through two different methods; the vapour liquid solid (VLS) method and an aqueous solution method. Each method had its own set of parameters and changes in those parameters influenced the output voltage of a nanogenerator. Changes in output voltage occurred as a result of variations in the resistance and the carrier concentration of grown nanowires as the piezoelectric charges were screened or trapped. An optimal value for both the resistance and the carrier concentration was determined in order to optimise the output voltage.

“…ZnO, II-VI Type compound semiconductor, is a direct band gap semiconductor that has the crystal structure of wurzite, a hexagonal form, like GaN, and possesses a wide band gap of 3.37 eV at room temperature. Since it has structural and optical properties similar with GaN, which is currently the most used semiconductor in LED and LD of short wave-length region, numerous researches are being carried out on the development of more stable and economic ZnO based LED [1][2][3]. Generally, ZnO takes the form of nonstoichiometry compound with the occurrences of defects such as interstitial Zn ion (Zn i…”

ZnO thin films which were deposited by RF magnetron sputtering system were annealed by furnace and insitu heat treatment methods. We investigated the effect of heat treatment method on physical properties of ZnO thin films. The structural and optical properties of ZnO thin films were improved by heat treatment. Through the annealing treatment of ZnO film by furnace, the good crystallinity and ultraviolet emission were obtained. These results are attributed to the improved formation of Zn-O bond in ZnO thin film annealed at by furnace. We confirm that the formation of Zn-O bond plays an important role in obtaining the excellent structural and optical properties of ZnO thin films.
