纳米级构建块与柔性和/或低成本衬底的合并可以使高性能电子和光子器件的开发成为可能，从而影响广泛的应用。在这里，我们展示了高质量的单晶纳米线可以组装到廉价的玻璃和柔性塑料基板上，以创建基本的晶体管和发光二极管器件。在我们的方法中，单晶纳米线的高温合成与基于环境温度溶液的组装分离，从而能够在几乎任何衬底上制造类似单晶的器件。硅纳米线场效应晶体管组装在玻璃和塑料基板上，显示器件参数可与单晶硅相媲美，并超过目前用于塑料基板上柔性电子产品的最先进的非晶硅和有机晶体管。纳米线晶体管器件已经被配置为具有增益的低阈值逻辑元件;此外，高性能特性相对不受弯曲配置中的操作或重复弯曲的影响。这种方法的一般性进一步说明了与柔性塑料基板上的氮化镓纳米线紫外线发光二极管的组件。这些结果表明，纳米线可以作为下一代轻量级显示器，移动的计算和信息存储应用的高性能构建块。
The merger of nanoscale building blocks with flexible and/or low cost substrates could enable the development of high-performance electronic and photonic devices with the potential to impact a broad spectrum of applications. Here we demonstrate that high-quality, single-crystal nanowires can be assembled onto inexpensive glass and flexible plastic substrates to create basic transistor and light-emitting diode devices. In our approach, the high-temperature synthesis of single-crystal nanowires is separated from ambient-temperature solution-based assembly to enable the fabrication of single-crystal-like devices on virtually any substrate. Silicon nanowire field-effect transistors were assembled on glass and plastic substrates and display device parameters rivaling those of single-crystal silicon and exceeding those of state-of-the-art amorphous silicon and organic transistors currently used for flexible electronics on plastic substrates. Nanowire transistor devices have been configured as low-threshold logic elements with gain; moreover, the high-performance characteristics are relatively unaffected by operation in a bent configuration or by repeated bending. The generality of this approach is further illustrated with the assembly of gallium nitride nanowire UV-light-emitting diodes on flexible plastic substrates. These results suggest that nanowires could serve as high-performance building blocks for the next of generation lightweight display, mobile computing, and information storage applications.
