The objective of this research is to interface Quantum-dot cellular automata (QCA) nanoelectronics and conventional electronics. As scaling of CMOS nears its end it is imperative to find new devices to overcome the problem of power density. Quantum-dot cellular automata is a promising new paradigm, however, silicon transistors have so many advantages that nanoelectronics must be made to interface to CMOS. The approach, a collaboration of groups at the University of Notre Dame and the University of Virginia, is to integrate conventional amplification and interface circuitry on-chip with nanoelectronic circuits grown using guided self-assembly of SiGe quantum dot molecules. The intellectual merit of the project is in its investigation of the little-explored interface of nanoelectronics and CMOS. Although power dissipation will limit CMOS in high-performance circuits, it will be used in circuit blocks far into the future. This project will move the field forward by integrating the growth of GeSi QCA cells into the CMOS fabrication sequence. Broader Impact: The proposed project will have a broader impact in both technology and education. Interfacing nanoelectronics and CMOS circuitry should enable the electronics industry to move beyond CMOS. The project will shape the experience of the graduate and undergraduate students through research, study, and mentoring others. An important component is an outreach program targeting middle school students through classroom activities, and field trips to bring students to the Notre Dame labs. Middle school aged children are an excellent group for outreach since they are still making choices about their areas of interests.

这项研究的目的是将量子点点细胞自动机（QCA）纳米电子学和常规电子设备进行接口。随着CMOS的缩放接近其末尾，必须找到新的设备来克服功率密度问题。量子点细胞自动机是一种有希望的新范式，但是，硅晶体管具有许多优势，必须使纳米电子学与CMOS接口。这种方法是巴黎圣母院和弗吉尼亚大学的团体的合作，是将传统的放大和接口电路与使用Sige量子点分子的指导自组装而种植的纳米电子电路整合。该项目的智力优点在于它研究了纳米电子和CMO的较小探索界面。 尽管功率耗散将限制高性能电路中的CMO，但它将在未来的电路块中使用。该项目将通过将GESI QCA细胞的生长整合到CMOS制造序列中来向前发展。更广泛的影响：拟议的项目将对技术和教育产生更大的影响。将纳米电子学和CMOS电路接口应使电子行业能够超越CMO。该项目将通过研究，研究和指导他人来塑造研究生和本科生的经验。 一个重要的组成部分是通过课堂活动针对中学生的推广计划，以及将学生带到巴黎圣母院实验室的实地考察。中学年龄的儿童是外展活动的绝佳团体，因为他们仍在选择自己的兴趣领域。
