A nanowire is an extremelythin wire with a diameter on the order of a few nanometers (nm) orless, where 1 nm = 10 to the minus 9th meters. A wire made from nanotubes. A nanowire allows a much lower current to flow compared to metal wire. See nanotube

严格来说就是在任一维度上的尺寸小于100nm的线状物,但现在的叫法比较混乱,不是十分严格。

请问该定义出自那一篇文章?

长径比

没有统一的定义。
现在的文献对纳米线和纳米棒很难分清楚。它们都是一维的纳米结构,其直径处于纳米级(1-100 nm),其长径比(长度与直径之比)大的称为纳米线,长径比小的称为纳米棒。但是长径比多大为线多小为棒还没有确切的定义。本人认为长径比20以下的都应该称为棒,因为看起来就不象线,充其量算线头,但是搞不懂很多人把长径比明显很短的棒也叫做线,此为纯粹炒作概念。

A nanowire is a wire of diameter of the order of a nanometer (10−9 meters). Alternatively, nanowires can be defined as structures that have a lateral size constrained to tens of nanometers or less and an unconstrained longitudinal size. At these scales, quantum mechanical effects are important — hence such wires are also known as "quantum wires". Many different types of nanowires exist, including metallic (e.g., Ni, Pt, Au), semiconducting (e.g., Si, InP, GaN, etc.), and insulating (e.g., SiO2,TiO2). Molecular nanowires are composed of repeating molecular units either organic (e.g. DNA) or inorganic (e.g. Mo6S9-xIx).

The nanowires could be used, in the near future, to link tiny components into extremely small circuits. Using nanotechnology, such components could be created out of chemical compounds.

你觉得这个定义准确吗?告诉你什么是棒什么是线了吗?
