摘要: In this study, we demonstrate a method for creating multi-length-scale ZnO nanowires in controllable manner on diverse planar and curvilinear substrates by introducing immiscible liquid masking layers (LMLs) above beneath nutrient solution used hydrothermal growth. The confinement of volatile reactants the LMLs stabilizes pH, which is an important parameter determining shape nanowires, to enable growth stable manner. conformal wettability provides freedom choice target allows possibility mounting spatially moving stages without use specially designed solid lid. Selective within zone defined dynamic- and/or static-mode can create various types with gradual or terraced length profiles two- three-dimensional geometries. For device application, developed cylindrical photodetectors configuration Cr/ZnO seed/ZnO nanowires/poly(3-hexylthiophene-2,5-diyl)/poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) show ability modulate photo-sensitivity controlled scales using LML method.
