NNCI: The Center for Nanoscale System (CNS) at Harvard University

哈佛大学纳米级系统中心（CNS）的目标是提供卓越的设施和专业知识来制造、成像和理解纳米级结构和系统。CNS提供了一个协作的、多学科的研究环境，允许来自学术界和工业界的研究人员研究和开发从生物医学到纳米电子学和光子学等领域的新结构、设备、系统和技术。CNS提供纳米制造、电子显微镜和纳米级系统表征工具，其工作人员提供技术专长和协助。CNS是世界上最活跃的纳米加工和成像设施之一，拥有1500多个用户，是东北高技术繁荣的重要组成部分。凭借其多样化的用户基础、完善的基础设施和出色的设备，CNS有能力继续成为技术领导者。此外，CNS在培养国家下一代科学家和工程师方面发挥着关键作用。它有一个成熟的本科生研究经验（REU）项目，以及一年一度的夏季纳米技术系列研讨会。一个新的中央神经系统学者项目将引进代表性不足的研究人员，一个实习项目将培训美国的纳米技术退伍军人。作为NNCI的一部分，CNS将有助于从纳米级器件的研究过渡到复杂的纳米系统工程。自2001年创建以来，CNS已成为国家关键的纳米技术资源。作为之前NNIN的一部分，CNS开发了多种多样的多功能设备，包括多长度尺度光学和电子束光刻，聚焦离子束（FIB）和反应离子蚀刻（RIE）系统来塑造结构，以及软光刻专业知识，以实现各种微流体系统的制造。这些工具允许用户使用非传统材料推动纳米级电子学和光子学的前沿，并使生物医学传感器系统的发展成为可能。CNS研究人员追求先进的课题，包括等离子体、钻石光子学、纳米级传感器和原子层器件。CNS拥有一套出色的成像和表征工具，包括像差校正STEM，高分辨率TEM， CryoTEM和用于3D断层扫描的原子探针，以及扫描探针显微镜，线性和非线性光学显微镜。它的表征工具允许对材料、组件和系统进行详细的分析和评估，为研究人员提供了纳米技术研究的综合平台。CNS专注于国家纳米技术计划（NNI）的核心任务：推进世界一流的纳米技术研究，促进新技术转化为商业和公共利益的产品，开发和维持教育资源以培养熟练的纳米技术劳动力，并支持不断发展的基础设施和先进工具，以支持卓越的纳米技术研究和开发。

The goal of the Center for Nanoscale Systems (CNS) at Harvard University is to provide outstanding facilities and expertise to make, image, and understand nanoscale structures and systems. CNS provides a collaborative, multi-disciplinary research environment that allows researchers from academia and industry to study and develop new structures, devices, systems, and technologies in fields ranging from biomedicine to nanoscale electronics and photonics. CNS offers tools for nanofabrication, electron microscopy, and characterization of nanoscale systems, with technical expertise and assistance provided by its staff. CNS is one of the most active nanofabrication and imaging facilities in the world with more than 1500 users, and it is an important part of the high-technology boom in the Northeast. With its diverse user base, well-established infrastructure, and outstanding facilities, CNS is well placed to continue as a technology leader. In addition, CNS plays a key role training the nation's next generation of scientists and engineers. It has an established Research Experiences for Undergraduates (REU) program, as well as an annual summer nanotechnology seminar series. A new CNS Scholars Program will bring in underrepresented researchers, and an internship program will train U.S. veterans in nanotechnology. As part of the NNCI, CNS will help make the transition from research on nanoscale devices to complex nanosystems engineering.Since its creation in 2001, CNS has become a key nanotechnology resource for the nation. As part of the previous NNIN, CNS developed diverse and versatile facilities including multi-length-scale optical and electron-beam lithography, focused ion beam (FIB) and reactive ion etch (RIE) systems to shape structures, and soft lithography expertise to enable fabrication of a wide variety of microfluidic systems. These tools allow users to push the frontiers of nanoscale electronics and photonics using nontraditional materials, and they enable the development of sensor systems for biomedicine. CNS researchers pursue advanced topics including plasmonics, diamond photonics, nanoscale sensors, and atomic-layer devices. CNS has an outstanding suite of imaging and characterization tools including an aberration-corrected STEM, a high resolution TEM, a CryoTEM, and an Atom Probe for 3D tomography, as well as scanned probe microscopes, and linear and non-linear optical microscopes. Its characterization tools permit detailed analysis and assessment of materials, components, and systems, providing researchers with a comprehensive platform for nanotechnology research. CNS focuses on the core missions of the National Nanotechnology Initiative (NNI): advancing world-class nanotechnology research, fostering the transfer of new technologies into products for commercial and public benefit, developing and sustaining educational resources to develop a skilled nanotechnology workforce, and supporting the evolving infrastructure and advanced tools needed to support excellence in nanotechnology research and development.
