****NON-TECHNICAL ABSTRACT****This Faculty Early Career Award supports an integrated research and education project to study the fundamental electronic properties of carbon based nanostructures using scanning probe microscopy. The research will focus on two carbon nanostructures: graphene, which is a two-dimensional sheet of carbon atoms and carbon nanotubes, which are one-dimensional, wire-like structures. These carbon nanostructures are candidates to replace silicon in future semiconductor technologies. Beyond their potential technological applications, these carbon materials exhibit many unique electronic properties due to their one and two-dimensional nature. By using scanning probe microscopy, this project will directly visualize, probe and control their unique electronic properties with nanometer scale resolution. The education portion of the project will bring the results of the research to local students through collaboration with the Physics Factory, which is a local non-profit organization. Undergraduate students will serve as mentors for high school students in order to build demonstrations of the research as well as other nanoscience topics. The demonstrations will be used by the Physics Factory during trips to K-12 schools. This collaboration will allow high school students through graduate students to be involved in the cutting-edge research. The results of the research will also be used in a new course for undergraduates focusing on experimental aspects of nanoscience.**** TECHNICAL ABSTRACT****This Faculty Early Career Award funds an integrated research and education project to study the fundamental electronic properties of carbon based nanostructures using scanning probe microscopy. The research will focus on single-walled carbon nanotubes and graphene which both exhibit unique electronic properties. In carbon nanotubes, the project will study aspects related to their one-dimensional nature such as spin-charge separation, reduced screening and inelastic scattering. In graphene, the project will look for ways to enable new functionality through the use of strain and electric fields. By combining scanning probe microscopy with electrical transport measurements, these electronic properties can be studied on the nanometer length scale. The research will be integrated with an outreach program to local K-12 schools. This will be accomplished through collaboration with a local non-profit organization, the Physics Factory. This project will enable the creation of a set of demonstrations about the research as well as broader areas of nanoscience to be used by the Physics Factory during visits to K-12 schools. The results of the research will also be used in a new course for undergraduates focusing on experimental aspects of nanoscience.

****非技术摘要****该教师早期职业奖支持一项综合研究和教育项目，以使用扫描探针显微镜研究碳基纳米结构的基本电子特性。 该研究将重点关注两种碳纳米结构：石墨烯（一种二维碳原子片）和碳纳米管（一种一维线状结构）。 这些碳纳米结构是未来半导体技术中替代硅的候选材料。 除了潜在的技术应用之外，这些碳材料由于其一维和二维性质而表现出许多独特的电子特性。 通过使用扫描探针显微镜，该项目将以纳米级分辨率直接可视化、探测和控制其独特的电子特性。 该项目的教育部分将通过与当地非营利组织物理工厂的合作，将研究成果带给当地学生。 本科生将担任高中生的导师，以展示该研究以及其他纳米科学主题。 物理工厂将在前往 K-12 学校期间进行演示。 此次合作将使高中生到研究生能够参与尖端研究。 研究结果还将用于本科生的新课程，重点关注纳米科学的实验方面。****技术摘要****该教师早期职业奖资助一个综合研究和教育项目，利用扫描探针显微镜研究碳基纳米结构的基本电子特性。 该研究将重点关注单壁碳纳米管和石墨烯，它们都表现出独特的电子特性。 在碳纳米管中，该项目将研究与其一维性质相关的方面，例如自旋电荷分离、减少屏蔽和非弹性散射。 在石墨烯中，该项目将寻找通过使用应变和电场来实现新功能的方法。 通过将扫描探针显微镜与电传输测量相结合，可以在纳米长度尺度上研究这些电子特性。 该研究将与当地 K-12 学校的推广计划相结合。 这将通过与当地非营利组织物理工厂的合作来完成。 该项目将创建一系列有关该研究以及更广泛的纳米科学领域的演示，供物理工厂在参观 K-12 学校期间使用。 研究结果还将用于本科生的一门新课程，重点关注纳米科学的实验方面。
