IDR: Self-Assembling Nanophotonic and Nanoelectronic Devices on DNA Nanobreadboards

摘要本研究的目的是开发一种新的自组装技术，用于制造纳米级光子和电子器件。方法是使用单链DNA，设计成自组装成二维“纳米板”。像量子点和金属纳米粒子这样的纳米粒子被精确地定位在彼此之间几纳米的距离内。智力优势：在这个项目中，将研究许多纳米级器件，如分束器、调制器和光电二极管，它们具有不同程度的合成复杂性。这些设备将使用pi最近开发的计算程序进行设计。该项目将有三个研究目标：1)设计短链DNA并合成适合器件组装的二维DNA纳米板；2)研究功能化纳米颗粒在DNA纳米板上的结合；3)利用光谱、飞行时间和脉冲I-V测量对所提出器件的光学和电学特性进行实验表征。更广泛的影响：主要的教育重点将放在跨学科领域的研究生和本科生身上。研究成果将被纳入最近开发的纳米科学/纳米技术课程，以迎合本地工业。我们需要在纳米技术和材料科学方面有更广泛知识的工程师。将招募代表性不足和未充分利用的群体参加该项目。学生将出席年度外展活动？博伊西州立日在州议会举行，纳米日在爱达荷州的探索中心举行。这项研究将对纳米级集成器件领域产生变革性的影响。它为超越那些已经成熟的新设备技术奠定了基础。

AbstractThe objective of this research is to develop a novel self-assembly technique for fabricating nanoscale photonic and electronic devices. The approach is to use a single strand DNA designed to be self-assembled into a two-dimensional ?nanobreadboard? where nanoparticles such as quantum dots and metal nanoparticles are positioned precisely within a few nanometers of each other.Intellectual Merit: In this project, a number of nanoscale devices such as a beamsplitter, modulator, and photodiode, with varying degree of synthesis complexity will be investigated. These devices will be designed with the computational program recently developed by the PIs. The project will address three research objectives: 1) design staple DNA strands and synthesize two-dimensional DNA nanobreadboard suitable for device assembly, 2) study the binding of functionalized nanoparticles on DNA nanobreadboard, and 3) experimentally characterize optical and electric properties of proposed devices using spectroscopy, time-of-flight, and pulsed I-V measurements.Broader Impact: A major educational focus will be on graduate and undergraduate students in an interdisciplinary field. Research results will be incorporated into the Nanoscience/Nanotechnology courses recently developed, catering to the local industry?s need for engineers with a broader knowledge in nanotechnology and materials science. Underrepresented and underutilized groups will be recruited to the project. Students will present at annual outreach events ? Boise State Day at the State Legislature and NanoDays at the Discovery Center of Idaho. The research will have a transformative impact on the field of nanoscale integrated devices. It lays the foundation for new device technologies beyond those that have matured.
