“…This indicates that the orientation of ZnO grown on stainless steel foils is not as consistent as that of ZnO grown on sapphire, 6H-SiC and GaN. 14,15 The polycrystalline nature of the stainless steel foils is believed to have a significant effect. Large orientation discrepancy exists among grains in polycrystalline materials, which can influence the orientation consistency of materials grown above.…”

PSS/PMMA/ZnO device was fabricated based on the grown ZnO nanorods. The metal-insulator-semiconductor type device shows an uncommon symmetric I-V curve. Under reverse bias, the device emits fairly pure UV light, which comes from the near band edge emission of ZnO. The working mechanism of the devices has been discussed, and a model mainly based on the Poole-Frenkel effect is proposed to describe the charge transportation of the devices.

“…Jung et al obtained ZnO nanorods on the various types of substrates using diethylzinc as the precursor, and argon as the carrier gas. The reactor temperature was at 500 °C [24]. The preparation and the modification of the shape and the size of ZnO nanostructures with the high adjustability of their geometry at room temperature are the main advantages of the electrochemical anodization method.…”

Abstract:One-dimensional metal oxide nanostructures such as nanowires, nanorods, nanotubes, and nanobelts gained great attention for applications in sensing devices. ZnO is one of the most studied oxides for sensing applications due to its unique physical and chemical properties. In this paper, we provide a review of the recent research activities focused on the synthesis and sensing properties of pure, doped, and functionalized ZnO quasi-one dimensional nanostructures. We describe the development prospects in the preparation methods and modifications of the surface structure of ZnO, and discuss its sensing mechanism. Next, we analyze the sensing properties of ZnO quasi-one dimensional nanostructures, and summarize perspectives concerning future research on their synthesis and applications in conductometric sensing devices.

“…ZnO nanorods grown by gas-phase synthesis technique (chemical vapor deposition (CVD) [7], metal organic chemical vapor deposition (MOCVD) [8] vapor-liquid-solid (VLS) [9] and pulsed laser deposition (PLD) [10] are reported to be perfectly aligned, homogeneously distributed with high crystallinity. But these methods require high processing temperature and also their development cost is very high.…”

The structural and optical properties of ZnO nanorods are investigated as a function of growth temperature of the seed layer. The seed layer comprising of ZnO nanocrystallites is grown on ITO substrates at five different temperatures (150-550 °C) and the nanorods are grown on the seed layer by the facile hydrothermal method. The seed layer grown at 350 ºC is observed to be uniformly textured with c-axis orientation leading to the synthesis of vertically aligned nanorods with smaller diameter. The HR-TEM analysis and the intense peak along (002) direction in the XRD spectra of this sample implied that the nanorods possess c-axis orientation. An enhanced UV emission is also observed in the photoluminescence spectra of this sample. The diversity in the morphology and orientation of the seeds at different temperatures has been explained by the growth kinetics of the ZnO nanocrystallites.
