NIRT: Electronic and Mechanical Devices from Graphene Films (NSF proposal ECS-0609243; P.C. Eklund, PI; Penn State University)This NSF NIRT project focuses on devices built from atomically thin carbon films comprised of a small number (n) of sp2-bonded carbon monolayers (i.e., n graphene-layer film or nGL). Fundamental investigation of the physical properties of these films will be made vs. n to assess how the confinement of electrons to atomically thin and narrow films (stripe geometry) will affect the electronic and mechanical properties. The stripe geometry will also be investigated for the development of chemical sensors where the exposed armchair or zigzag graphene edges are functionalized with end groups that will bind to specific analytes. Intellectual Merit: We will also investigate the production of highly conducting circuit-interconnects based on doped graphene which theory argues should show promise as 2D supermetals. AFM-based local probe studies, such as scanned gate microscopy and electric force microscopy, will be used to investigate carrier scattering mechanisms and linear dispersion relation in a nGL FETs, respectively. Atomically thin GL stripes and membrane devices will be investigated, respectively, for actuators (nano-muscle) and ultra-sensitive mass detectors. Both of these mechanical devices will require a detailed measurement and understanding of the elastic modulus of nGLs vs n. A strong theoretical component has been built into the project to help elucidate the many physical properties and device behaviors that we will observe in this new class of atomically thin films. Broader Impacts: We will focus our outreach on the creation of educational units for summer science camps K-16 students. To optimize this activity, we will once again affiliate with the established Action Potential Science Experience (APSE) program, a K-16 Penn State outreach and service-learning program where university faculty, researchers, graduate and undergraduate students will teach hands-on, science-based laboratories during the summer.

NIRT：石墨烯薄膜的电子和机械器件(NSF提案ECS-0609243；P.C.埃克伦德，PI；宾夕法尼亚州立大学)该NSF NIRT项目专注于由少量sp2结合的碳单分子层(即n石墨烯层薄膜或ngl)组成的原子薄碳膜构建的器件。我们将对这些薄膜的物理性质进行基础研究，以评估电子对原子薄而窄的薄膜(条纹几何形状)的限制将如何影响电子和机械性能。为了开发化学传感器，还将研究条纹几何形状，其中暴露在扶手椅或锯齿形石墨烯边缘的端基将与特定分析物结合在一起。智力优势：我们还将研究基于掺杂石墨烯的高导电电路互连的生产，理论上认为，这种材料作为2D超级金属应该会有希望。基于AFM的局部探针研究，如扫描栅显微镜和电场力显微镜，将分别用于研究NGL FET中的载流子散射机制和线性色散关系。原子薄GL条和薄膜器件将分别用于执行器(纳米肌肉)和超灵敏质量探测器。这两种机械装置都需要对NGL与n的弹性模数进行详细的测量和了解。该项目中建立了一个强大的理论组件，以帮助阐明我们将在这类新的原子薄膜中观察到的许多物理特性和器件行为。更广泛的影响：我们将把我们的宣传重点放在为K-16岁的学生建立科学夏令营的教育单元上。为了优化这一活动，我们将再次加入既定的行动潜在科学体验(APSE)计划，这是宾夕法尼亚州立大学K-16年级的一个外展和服务学习计划，大学教职员工、研究人员、研究生和本科生将在暑期教授以科学为基础的动手实验室。
