Abstract & Overview
This paper presents the recent advances of the ZnO nanowires based sensors. ZnO has gained a substantial interest in the research areas of the wide band gap semiconductors due to its unique electrical, optical and structural properties. ZnO is considered as one of the major candidates for several electronic and photonic applications. ZnO is considered as a potential contender in optoelectronic applications such as solar cells, surface acoustic wave devices, and ultraviolet (UV) emitters. ZnO as a nanostructured material exhibits many advantages for nanodevices. ZnO nanostructured material has the ability to absorb the UV radiation. ZnO nanowires have received a considerable attention due to the morphological changes with doping. ZnO nanowires are very attractive material for nano-sensors due to their properties induced by the quantum size effects. Recently, ZnO nanowires based devices have gained much attention due to their various potential applications in nanoelectronics devices including gas sensors, nanogenerators, and nano-lasers. The recent aspects of ZnO nanowires based sensors devices are presented and discussed.
