Nanowires offer a unique approach for the bottom up assembly of electronic and photonic devices with the potential of integrating photonics with existing technologies. The anisotropic geometry and mesoscopic length scales of nanowires also make them very interesting systems to study a variety of size-dependent phenomenon where finite size effects become important. We will discuss the intriguing size-dependent properties of nanowire systems with diameters in the 5 - 300 nm range, where finite size and interfacial phenomena become more important than quantum mechanical effects. The ability to synthesize and manipulate nanostructures by chemical methods allows tremendous versatility in creating new systems with well controlled geometries, dimensions and functionality, which can then be used for understanding novel processes in finite-sized systems and devices.
纳米线为自下而上组装电子和光子器件提供了一种独特的方法，具有将光子学与现有技术集成的潜力。纳米线的各向异性几何形状和介观长度尺度也使它们成为研究各种尺寸依赖性现象的非常有趣的系统，在这些现象中，有限尺寸效应变得很重要。我们将讨论直径在5 - 300纳米范围内的纳米线系统有趣的尺寸依赖性特性，其中有限尺寸和界面现象比量子力学效应更为重要。通过化学方法合成和操纵纳米结构的能力，使得在创建具有精确控制的几何形状、尺寸和功能的新系统方面具有极大的通用性，这些新系统随后可用于理解有限尺寸系统和器件中的新过程。
