The objective of this research is to develop an understanding of how nanometer scale (one billionth of a meter) structures affect electrical contact resistance and useful life. It is known that rough surfaces wear quickly, but how smooth should surfaces be to make better electrical contacts for switches and relays? The approach is to test surfaces with nanometer-scale roughness to which are applied thin-film coatings, including carbon nanotubes grown directly on the contact testing along with a special apparatus for evaluating coated surfaces samples to choose candidate materials for high-cycle testing. The contracts will be evaluated at regular intervals to develop an understanding of their long-term surface behavior. Mathematical models will be made to predict performance and used to help design longer lasting lower resistance miniature electrical switches.The societal impact of this research includes educational and industrial benefits. Modern society cannot function without electronics, and electronic devices cannot function without reliable high quality switches. As electronics shrink, so must the switches. Educationally, a recent MIT Ph.D. graduate, who has been teaching inner-city high school students, and students, from OSU and MIT will work together to develop new nanoscience-centered teaching materials for use in core math an science classes. Industrially, this research will enable the creation of lower resistance longer life electrical contacts. The industrial partner will be able to make smaller electrical probes for testing silicon microchips.

这项研究的目的是对纳米量表（米三分之一的尺度）结构如何影响电气电阻和有用寿命有一种理解。 众所周知，粗糙的表面很快磨损，但是要为开关和继电器做出更好的电气触点的表面应该如何光滑？ 该方法是用纳米尺度粗糙度测试表面，这些粗糙度是施加的薄膜涂层，包括直接在接触式测试上生长的碳纳米管以及一种特殊的设备，用于评估涂层表面样品以选择候选材料进行高循环测试。 合同将定期评估，以发展对其长期表面行为的理解。 将制定数学模型来预测性能，并用于帮助设计更长的持久较低的电阻微型电气开关。这项研究的社会影响包括教育和工业利益。 如果没有电子设备，现代社会就无法运作，并且没有可靠的高质量开关，电子设备将无法运行。 随着电子设备收缩，开关也必须如此。 在教育上，最近的麻省理工学院博士OSU和MIT的研究生教授来自OSU和MIT的学生和学生，将共同开发新的以纳米科学为中心的教学材料，以在核心数学和科学课程中使用。 从工业上讲，这项研究将使较低的阻力更长的寿命电气接触。 工业伙伴将能够制作较小的电探针来测试硅微芯片。
