This paper presents the advances of Zinc Oxide (ZnO) devices. Due to its unique properties, ZnO has gained a substantial intension in the advancement of semiconductor-device technologies. ZnO is considered as one of the major candidates for several electronic and photonic applications. Many research has been conducted about ZnO and its contributions in several high-tech semiconductors fabrications that will take the technology of electronics to a higher level in several applications. ZnO nanostructured material can absorb UV radiation. ZnO nanowires have received 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. This paper presents and discusses the importance of ZnO in the advancement of nanowire-based gas sensors. Applications of the ZnO in technology in solar cells will be introduced as well in addition to other applications and designs of other devices such as UV-photodetection and Nanorods application in wave transmissions.
