NER: Colloidal Crystals for Nanoelectronic Device Fabrication

这项研究的目的是利用胶体晶体模板来设计创新的纳米电子器件结构。胶体模板方法的独特性能使其适用于需要较大结区/表面积或两种材料的纳米级混合物的纳米电子器件结构的制造。方法是通过制造三个纳米电子材料原型来确定这项技术的能力。第一，超结二极管，其中互锁的p和n型半导体晶格产生具有高阻断电压和低电阻的整流器；第二，热电子材料，其中跨越晶体的量子限制导致极大地提高热电子优值；第三，电池阴极，它将两个阴极材料缠绕在一起，以同时提高容量和稳定性。研究将表明，胶体晶体模板技术的独特能力使其成为制造纳米电子器件的廉价和容易的方法，否则将需要昂贵和复杂的制造过程来制造。这项提案中的探索性研究是肯塔基州加强纳米研究和教育的长期计划的一部分。高中生将通过纳米技术研究员计划和基于纳米技术的科学项目的开发来接受纳米技术方面的教育。将利用与肯塔基州和全国各地的工业界的接触，为拟议的胶体制造技术开发商业应用。

The objective of this research is to employ colloidal crystalline templating to engineer innovative nanoelectronic device structures. The unique capabilities of the colloidal templating method make it suitable for fabrication of nanoelectronic device structures in which large junction areas / surface areas or a nanometer-level mixture of two materials is needed. The approach is to establish the capabilities of this technique through the fabrication of three nanoelectronic material prototypes. First, a superjunction diode in which interlocking p and n type semiconductor lattices produce a rectifier with high blocking voltages and low on resistance; second, a thermoelectronic material in which quantum confinement across the crystal leads to a greatly enhanced thermoelectronic figure of merit; and third, a battery cathode that intertwines two cathodes materials to simultaneously enhance capacity and stability.The investigation will show that the unique capabilities of the colloidal crystalline templating technique make it a cheap and easy method for the fabrication of nanoelectronic devices that would otherwise require expensive and elaborate fabrication procedures to produce. The exploratory research in this proposal forms part of a long-term plan to enhance nanoscale research and education in the state of Kentucky. High school students will be educated in nanotechnology through a Nanotech Fellows program and development of nanotechnology based science projects. Outreach to the industrial community both within Kentucky and around the country will be used in developing commercial applications for the proposed colloidal fabrication technique.
