Nature has the ability to produce structures that are finer in detail than the reach of humankind. For example the elaborate pattern of frost that appears on a single pane window on a winter's day self-assembles through the subtle interactions between water molecules and the glass surface. Similarly, in our lab, we guide nature to make metallic wires (nanowires) that are a hundred times thinner than what is possible by conventional means. Our lab, along with many others world wide, have developed many of these nanomaterials that have unique electronic properties. The question is how to build these materials into circuits or devices, or how to electrically interface the nanoworld with our macro world. In the parlance of nanotechnology, self-assembly is a "bottom up" approach to making nanometer scale structures, while the current microelectronic industry is based on lithography and thin film growth that are "top down" methods for making electrical circuits. Development of nanoscale electronics will rely on a combination of bottom up and top down fabrication. We are developing an integrated combination of these techniques to make and to study nanostructures that are built into circuits for electrical testing. These techniques will be applicable to broad classes of electronic nanomaterials and will enable the development of future nanodevices.

大自然有能力制造出比人类所能达到的更精细的结构。例如，冬日里出现在一扇玻璃窗上的霜的复杂图案，是通过水分子和玻璃表面之间的微妙相互作用而自我组装起来的。同样，在我们的实验室里，我们引导自然界制造出比传统方法薄一百倍的金属线（纳米线）。我们的实验室，沿着与世界各地的许多其他实验室一起，已经开发出许多具有独特电子特性的纳米材料。问题是如何将这些材料构建成电路或设备，或者如何将电子世界与我们的宏观世界连接起来。 在纳米技术的术语中，自组装是一种“自下而上”的方法来制造纳米尺度的结构，而目前的微电子工业是基于光刻和薄膜生长，这是一种“自上而下”的方法来制造电路。纳米级电子器件的发展将依赖于自下而上和自上而下制造的结合。我们正在开发这些技术的综合组合，以制造和研究内置于电路中的纳米结构，用于电气测试。这些技术将适用于广泛的电子纳米材料类别，并将使未来的纳米器件的发展。
