This Perspective presents a review of current research activities on one-dimensional (1D) semiconductor nanostructures grown on two-dimensional (2D) nanomaterials for flexible electronic and optoelectronic device applications. For hybrid-dimensional nanostructures, 1D nanostructures exhibit excellent material characteristics, including high carrier mobility and radiative recombination rate as well as long-term stability, while 2D layers show good optical transparency, mechanical flexibility, and electrical characteristics. Accordingly, the versatile and fascinating properties of 1D nanostructures grown on 2D layers enable the fabrication of high-performance optoelectronic and electronic devices even in transferable, flexible, or stretchable forms. We initially present a variety of 1D/2D hybrid nanostructures and their preparation methods, followed by a discussion of techniques for fabricating aligned 1D nanostructure arrays on 2D layers and their heterostructures. Furthermore, we discuss a wide range of devices based on the 1D/2D hybrid nanostructures. These devices include light-emitting devices, photodetectors, transistors, and pressure sensors. Several important issues, including 1D/2D junction properties and device fabrication processes for device applications, are also addressed. We conclude with personal remarks on the issues and perspectives for research on 1D/2D hybrid nanostructures for more sophisticated device applications.

用于柔性器件应用的二维纳米材料上生长的一维半导体纳米结构

本视角回顾了当前在二维 (2D) 纳米材料上生长的一维 (1D) 半导体纳米结构的研究活动,用于柔性电子和光电器件应用。对于混合维纳米结构,一维纳米结构表现出优异的材料特性,包括高载流子迁移率和辐射复合率以及长期稳定性,而二维层则表现出良好的光学透明度、机械柔韧性和电学特性。因此,生长在 2D 层上的 1D 纳米结构的多功能和引人入胜的特性使制造高性能光电和电子设备成为可能,即使是可转移、柔性或可拉伸的形式。我们最初介绍了各种一维/二维混合纳米结构及其制备方法,随后讨论了在 2D 层及其异质结构上制造对齐的 1D 纳米结构阵列的技术。此外,我们讨论了基于 1D/2D 混合纳米结构的各种设备。这些器件包括发光器件、光电探测器、晶体管和压力传感器。还解决了几个重要问题,包括用于器件应用的 1D/2D 结特性和器件制造工艺。最后,我们对用于更复杂设备应用的 1D/2D 混合纳米结构的研究问题和观点进行了个人评论。这些器件包括发光器件、光电探测器、晶体管和压力传感器。还解决了几个重要问题,包括用于器件应用的 1D/2D 结特性和器件制造工艺。最后,我们对用于更复杂设备应用的 1D/2D 混合纳米结构的研究问题和观点进行了个人评论。这些器件包括发光器件、光电探测器、晶体管和压力传感器。还解决了几个重要问题,包括用于器件应用的 1D/2D 结特性和器件制造工艺。最后,我们对用于更复杂设备应用的 1D/2D 混合纳米结构的研究问题和观点进行了个人评论。
