Facile meniscus dragging depositions for lateral alignment of ZnO nanowires

Abstract

© 2017, Korean Physical Society. We fabricated laterally-aligned ZnO nanowires by using the meniscus dragging deposition (MDD) technique under various deposition conditions. The ZnO nanowire alignment exhibits a linear response with increasing number of deposition cycles, indicating that the deposited ZnO nanowires were tightly fixed on the substrate and showing that the degree of alignment was constant at ∼65%. Also, we could regulate the density and the degree of alignment by controlling the deposition angle, temperature and speed. The MDD technique for fabricating laterally-aligned ZnO nanowires can be useful for synthesizing functional materials in numerous electronic and optoelectronic devices, including field-effect transistors, nanogenerators and ultraviolet sensors.
