Technical abstract: The development of a new research instrument for nanoscale elemental analysis and materials modification using scattering of noble gas ions creates opportunities for materials science unachievable to date. Intellectual challenges include the creation of the tool, understanding energetic ion-solid interactions with a nano-beam, and applications, both in materials analysis and materials modification. Our project integrates two recent technological developments: Focused nanoscale ion beams available as the Zeiss ORION® He microscope and picosecond timing electronics with high throughput by Ionwerks®. Analysis applications include the first ion beam interrogation of individual nanostructures and determinations of lateral film uniformity. The instrument will also be used for materials modifications such as graphene based counters for single molecule analysis, development of qubit based superconducting junctions for quantum computing and studies of the behavior of defects within nano-structured materials. Also included is the development of nanoscale Ne beams for materials modification and sample preparation, an entirely new ion beam capability. Such beams may be used for ion milling on the nm scale, semiconductor amorphization and implantation with nm precision, spatial control of 'single ion upsets' in electronic devices, new tests of inter-granular defects for fusion applications and the creation of new materials from ion-carved graphene and other two dimensional materials. Non-technical abstract: Nanoscale materials have an enormous impact on basic and applied science. Unanticipated phenomena and functionalities are being discovered and exploited commercially at an ever increasing pace. New experimental tools are therefore needed to reliably perform materials characterization and modification at the same level. This project introduces a significant advance through the development of a versatile ion beam facility for true nano-scale ion spectroscopy, ion beam materials modification and ion beam milling. The project integrates new ion beam technologies to allow analysis of individual nano-particles as well as materials modification of nanostructures and ion sculpting and milling with unprecedented spatial control, involving the development of a new, heavy ion nano-beam. This represents a leap in ion beam oriented materials science. New science and technology is anticipated such as the investigation of the ligand binding of gold nanoparticles used in cancer drug delivery, the creation of nanometer orifices to explore DNA sequencing and the formation of quantum structures for advanced computing and communications.The direct and visually oriented nature of the information from this instrument will illustrate the excitement of materials science to students ranging from middle school to advanced graduate students through a well developed local infrastructure. As Rutgers has an extraordinarily diverse student body, the project will be particularly useful in attracting underrepresented groups. The instrument will provide excellent opportunities for hands-on experience in the development and use of sophisticated scientific equipment for undergraduate students and enrich the graduate curriculum. The general public will be involved through open houses and lectures. As a 'one of a kind' instrument this instrument will attract world leaders in the diverse fields addressed by nano-materials. Together with other recent NSF awarded instrumentation, this instrument will establish Rutgers as a national center for nano-scale microscopy.

技术摘要：开发一种新的研究仪器，用于纳米级元素分析和使用惰性气体离子散射的材料改性，为材料科学创造了迄今为止无法实现的机会。智力挑战包括工具的创建，理解高能离子与纳米束的相互作用，以及在材料分析和材料改性方面的应用。我们的项目整合了两项最新的技术发展：蔡司ORION® He显微镜提供的聚焦纳米级离子束和Ionwerks®提供的高通量皮秒计时电子器件。分析应用包括单个纳米结构的第一离子束询问和横向膜均匀性的测定。该仪器还将用于材料改性，例如用于单分子分析的石墨烯计数器，用于量子计算的量子位超导结的开发以及纳米结构材料中缺陷行为的研究。还包括纳米级Ne束的材料改性和样品制备，一个全新的离子束能力的发展。这样的射束可以用于纳米尺度的离子铣削、纳米精度的半导体非晶化和注入、电子器件中的“单离子扰乱”的空间控制、用于聚变应用的颗粒间缺陷的新测试以及从离子雕刻的石墨烯和其他二维材料产生新材料。 非技术摘要：纳米材料对基础科学和应用科学产生了巨大的影响。意想不到的现象和功能正在以越来越快的速度被发现和商业化利用。因此，需要新的实验工具来可靠地进行材料表征和相同水平的改性。该项目介绍了一个重要的进步，通过一个多功能的离子束设备的发展，真正的纳米尺度离子光谱，离子束材料改性和离子束铣削。该项目集成了新的离子束技术，可以分析单个纳米颗粒以及纳米结构的材料改性和离子雕刻和铣削，具有前所未有的空间控制，涉及新的重离子纳米束的开发。这代表了离子束导向材料科学的飞跃。 新的科学和技术是预期的，如研究用于癌症药物输送的金纳米颗粒的配体结合，创造纳米孔来探索DNA测序和量子结构的形成，用于先进的计算和通信。从这台仪器中直接和视觉导向的信息将说明材料科学对从中学到高等教育的学生的兴奋学生通过当地发达的基础设施。由于罗格斯大学拥有非常多样化的学生群体，该项目将特别有助于吸引代表性不足的群体。该仪器将为本科生提供开发和使用尖端科学设备的实践经验的绝佳机会，并丰富研究生课程。公众将通过开放日和讲座参与。作为一种“独一无二”的仪器，该仪器将吸引纳米材料所涉及的各个领域的世界领导者。连同其他最近NSF授予仪器，该仪器将建立罗格斯大学作为国家中心的纳米尺度显微镜。
