This award from the Instrumentation for Materials Research program will enable groundbreaking experiments that seek to apply the "bottom-up" approach of atomic and molecular manipulation to several focused areas in science and technology. The primary experimental apparatus for these investigations is a custom-built low-temperature scanning probe microscope capable of both studying and controlling matter at atomic length scales. The tunneling mode of the apparatus will be exploited to perform scanning tunneling microscopy (STM) within an environment comprised of ultra-high vacuum, ultra-low temperature down to 500 mK, a high magnetic field up to 14 T, and a multiple-probe sample stage for performing simultaneous electron transport measurements. Achieving these challenging conditions requires the acquisition of the specialized equipment described in this award. Undergraduate and graduate students working directly on these projects will integrate and operate the proposed instrumentation to perform state-of-the-art experiments. In synergy with these laboratory components, this instrumentation will critically augment a substantial educational and outreach program already being implemented by the PI and Stanford University.%%%This award from the Instrumentation for Materials Research program will enable groundbreaking experiments that seek to apply the "bottom-up" approach of atomic and molecular manipulation to several focused areas in science and technology. This scientific effort is interdisciplinary in nature, centering on physics and materials science but involving ideas, techniques, and conundrums from other fields such as chemistry, engineering, and information technology. The primary experimental apparatus for these investigations is a custom-built scanning probe microscope capable of both studying and controlling matter at atomic length scales, requiring the acquisition of the specialized equipment described in this award. Undergraduate and graduate students working directly on these projects will integrate and operate the proposed instrumentation to perform state-of-the-art experiments. In synergy with these laboratory components, this instrumentation will critically augment a substantial educational and outreach program already being implemented by the PI and Stanford University. Through these multifaceted contacts between the research agenda, students, and people outside the laboratory, the proposed instrumentation will have a broad and unique impact beyond the traditional realm of experimental science. In recognition of the importance of this award, Stanford University is providing cost-sharing funds amounting to 50% of the funds provided by NSF.

材料研究仪器仪表计划的这一奖项将实现突破性的实验，寻求将原子和分子操纵的“自下而上”方法应用于科学和技术的几个重点领域。 这些研究的主要实验设备是定制的低温扫描探针显微镜，能够在原子长度尺度上研究和控制物质。 该设备的隧道模式将用于在超高真空、低至 500 mK 的超低温、高达 14 T 的高磁场和用于同时进行电子传输测量的多探针样品台组成的环境中执行扫描隧道显微镜 (STM)。 实现这些具有挑战性的条件需要购买该奖项中描述的专用设备。 直接从事这些项目的本科生和研究生将集成和操作拟议的仪器来执行最先进的实验。 通过与这些实验室组件的协同作用，该仪器将极大地增强 PI 和斯坦福大学已经实施的实质性教育和推广计划。%%%材料研究仪器计划的这一奖项将实现突破性的实验，寻求将原子和分子操纵的“自下而上”方法应用于科学和技术的几个重点领域。 这项科学工作本质上是跨学科的，以物理学和材料科学为中心，但涉及化学、工程和信息技术等其他领域的思想、技术和难题。 这些研究的主要实验设备是定制的扫描探针显微镜，能够在原子长度尺度上研究和控制物质，需要购买该奖项中描述的专用设备。 直接从事这些项目的本科生和研究生将集成和操作拟议的仪器来执行最先进的实验。 通过与这些实验室组件的协同作用，该仪器将极大地增强 PI 和斯坦福大学已经实施的实质性教育和推广计划。 通过研究议程、学生和实验室外人员之间的多方面接触，所提出的仪器将产生超越传统实验科学领域的广泛而独特的影响。 考虑到该奖项的重要性，斯坦福大学将提供相当于 NSF 所提供资金 50% 的费用分摊资金。
