This paper proposes the development of a research and educational program to further the knowledge and understanding of nanotechnology through laboratory, classroom, project, and demonstration experiences. A directed effort toward the development of nanowire devices and circuits is proposed, utilizing the self-assembly of nanowires through the vapor-liquid-solid (VLS) technique. The merit of this work is in the investigation of an additional control mechanism through the use of electrostatic forces to join individual nanowires, and the development of a procedure for epitaxially interconnecting to the nanowires from macroscopic electrodes. Investigations will include nanowire p-n junctions, field effect transistors, light emitting diodes, and heterojunction devices. Using the VLS technique to fabricate nanowire interconnects may also prove a viable method of interfacing to molecular electronic circuits, for the fabrication of scanning probes used in scanning tunneling microscopy, or atomic force microscopy, and for making micro-electromechanical systems (MEMS) such as electrical conductivity probes.This proposal outlines three methods of extending the scholarly impact beyond the students directly involved in the research, to include other graduate students, undergraduate students, and local area schools. A course has been developed around future directions in semiconductor devices including nanotechnology that will be further expanded upon. Second, scanning probe tips will be fabricated as part of this effort, and a group of undergraduates will be assisted in building a working scanning probe microscope (SPM). The third outreach effort includes using the fabricated SPM for both on-campus and off campus demonstrations at local high schools and middle schools.

本文提出了一个研究和教育计划的发展，通过实验室，课堂，项目和示范经验，以进一步的知识和纳米技术的理解。 提出了利用纳米线通过气-液-固（VLS）技术的自组装来开发纳米线器件和电路的定向努力。 这项工作的优点是在一个额外的控制机制，通过使用静电力加入个别纳米线的调查，和外延互连的纳米线从宏观电极的程序的发展。 研究将包括纳米线p-n结，场效应晶体管，发光二极管和异质结器件。 使用VLS技术制造纳米线互连也可能被证明是一种可行的方法，用于连接分子电子电路，用于制造扫描隧道显微镜或原子力显微镜中使用的扫描探针，以及用于制造微机电系统（MEMS），如电导率探针。该提案概述了三种方法，将学术影响扩展到直接参与研究的学生之外，包括其他研究生、本科生和当地学校。 围绕半导体器件的未来发展方向，包括纳米技术，将进一步扩大。 第二，扫描探针尖端将制造作为这项工作的一部分，一组本科生将协助建立一个工作扫描探针显微镜（SPM）。 第三个推广工作包括在当地高中和中学使用制作的SPM进行校内和校外示威。
