Conductive, transparent, and flexible SnO2:Sb single-crystal nanowires are shown as electrodes for F16CuPc single-crystal nanowire devices on flexible plastic, which includes anisotropic-transport OFETs, electrode-movable OFETs, and p–n junction photovoltaic devices. The SnO2:Sb nanowires provide a good energy level match and excellent soft contact with F16CuPc nanowires, leading to multifaceted applications of the SnO2:Sb nanowire in nanowire electronics and optoelectronics, as well as high device performance. Combined with their good size compatibility, these results show that the conductive SnO2:Sb single-crystal nanowire opens a window into the fundamental understanding of the intrinsic properties of highly ordered organic semiconductors, optimization and miniaturization of organic nanocircuits, and development of new-generation flexible organic nanodevices.

A multiple drop-casting method of growing the ultralong dibenzo-tetrathiafulvalene (DB-TTF) micro/nanowire arrays has been developed which has the success ratio as high as 94%. This method enables the arrays with a length over a few hundreds of micrometers to locate between droplets with the definite orientation. The width of the micro/nanowires is controlled via tuning the concentration of DB-TTF solution in dichloromethane. The large-scale arrays can be grown onto Si, SiO2, glass, and the flexible polyethylene terephthalate (PET) substrates. These results show the promising potential of this facile solution-based process for the growth of the high-quality organic micro/nanowires, the fabrication of high-performance and flexible devices, and the fabrication of controlled assemblies of nanoscale circuits for fundamental studies and future applications.

•We developed the drop-casting method via saturated solvent atmosphere, and obtained the single-crystal TTF microwire arrays.•Based on this method, the success ratio to form TTF microwire arrays is as high as 86%.•This method can improve the crystalline quality and success ratio of many soluble organic microwire arrays, such as TTF, DB-TTF and TCNQ.•The TTF microwire array FETs were fabricated based on this method, suggesting the potential of this method in electronic applications.We developed a drop-casting method to grow the well-aligned single-crystal tetrathiafulvalene (TTF) microwire arrays with success ratio as high as 86%. The key improvement over the earlier study is that the substrate is placed in an apparatus which is filled with the saturated solvent vapor at room temperature. The saturated solvent atmosphere ensures stable environment and adequate time to form the arrays with high success ratio, and to dramatically improve the crystalline quality. Combined with the optimized concentration, the highly ordered single-crystal TTF microwire arrays are obtained. Based on these microwire arrays, the assembly of devices can be easily realized in one step. These results show the potential of this facile method to form the high-quality arrays, and the assemblies of nanoscale circuits for fundamental studies and future applications.The large-scale, well-aligned and single-crystal tetrathiafulvalene (TTF) microwire arrays have been obtained by the developed drop-casting method in the saturated solvent atmosphere with high success ratio.

The ultralong ZnO nanowires have been obtained by using ZnO and graphite as the mixture source via the catalyst-free vapor–solid (VS) process at 917 °C. The ZnO nanowires are over 100 μm in length and ∼100–300 nm in diameter with uniform hexagonal cross section. The single ultralong ZnO nanowire grows on the top of one ZnO nanotower with the length of ∼5 μm and the diameter of ∼600 nm. The formation of a ZnO hard layer on the surface of the mixture source is responsible for the abrupt morphology change and the growth of the ultralong nanowires. The local concentration of the Zn vapor and the oxygen are found to be critical for the formation of the ultralong ZnO nanowires. The catalyst-free growth of the ultralong ZnO nanowire was carried out with good repeatability in a low-cost quartz tube electric resistance furnace with the temperature lower than 1000 °C, showing a promising potential for the development of the ZnO based nanodevices and nanocircuits.
