The Instrumentation for Materials Research (IMR) funding provided to this program will be used to purchase a Micromanipulated Cryogenic Probe Station. This instrument will facilitate temperature-dependent characterization of a variety of materials and devices being fabricated in the Penn State Materials Research Science and Engineering Center for Nanoscale Science including ferroelectric thin films and nanotubes, semiconductor and superconductor nanowires, and metal-molecule-metal junctions. These measurements will provide insight into fundamental materials properties such as domain wall motion in scaled ferroelectric thin films and electrical transport in one-dimensional nanostructures. This system offers advantages over conventional cryostats for these samples because it eliminates potentially damaging device packaging (i.e., dicing, mounting, and wire bonding) steps by incorporating six independently controlled micro-manipulated low-noise probes that are used to contact devices across a large sample diameter. In addition, the ability to probe multiple devices in a single cool down will make it easier to collect data on device-to-device variations, which have proven to be significant in many new nanoscale materials such as those described here. The cryogenic probe system will also have broader educational impact in undergraduate research and laboratory-based coursework. Several new laboratory modules will be incorporated into existing undergraduate and graduate physics and electrical engineering courses to provide instruction on temperature-dependent measurement of physical effects in nanoscale materials and devices.The Instrumentation for Materials Research (IMR) funding provided to this program will be used to purchase a Micromanipulated Cryogenic Probe Station. This instrument incorporates six independently controlled probes that are used to contact individual on-chip devices, which are maintained at temperatures between 4 and 300 K by a continuous flow liquid helium cryostat.

为该计划提供的材料研究仪器 (IMR) 资金将用于购买显微操作低温探针站。 该仪器将促进宾夕法尼亚州立大学纳米科学材料研究科学与工程中心制造的各种材料和器件的温度依赖性表征，包括铁电薄膜和纳米管、半导体和超导体纳米线以及金属-分子-金属结。 这些测量将提供对基本材料特性的深入了解，例如缩放铁电薄膜中的畴壁运动和一维纳米结构中的电传输。 对于这些样品，该系统比传统低温恒温器具有优势，因为它通过合并六个独立控制的微操作低噪声探针（用于跨大范围接触器件），消除了可能损坏器件的封装（即切割、安装和引线键合）步骤。样品直径。 此外，在一次冷却中探测多个设备的能力将使收集设备间变化的数据变得更加容易，这已被证明在许多新的纳米级材料（例如此处描述的材料）中具有重要意义。 低温探针系统还将对本科生研究和实验室课程产生更广泛的教育影响。 几个新的实验室模块将被纳入现有的本科生和研究生物理和电气工程课程中，以提供有关纳米级材料和器件中物理效应的温度相关测量的指导。将使用为该项目提供的材料研究仪器（IMR）资金购买显微低温探针台。 该仪器包含六个独立控制的探针，用于接触各个片上器件，这些器件通过连续流液氦低温恒温器将温度维持在 4 至 300 K 之间。 该探针站将促进宾夕法尼亚州立大学纳米科学材料研究科学与工程中心制造的各种新器件的温度依赖性表征，包括铁电薄膜和纳米管、半导体和超导体纳米线以及金属-分子-金属结。 这些测量将提供对基本材料特性的深入了解，例如缩放铁电薄膜中的畴壁运动和一维纳米结构中的电传输。 低温探针系统还将对本科生研究和实验室课程产生更广泛的教育影响。 几个新的实验室模块将被纳入现有的本科生和研究生物理和电气工程课程中，以提供有关纳米材料和设备中物理效应的温度相关测量的指导。
