美国麻省理工学院材料科学与工程系博士后研究员陆洋博士将于9月15日到我校金属材料强度国家重点实验室微纳尺度材料与行为研究中心(CAMP-Nano)交流访问,届时将做精彩报告。
报告时间:2011年9月15日(周四)上午10:00
报告地点:材料学院/金属材料强度国家重点实验室215会议室
报告题目:
In Situ Quantitative Mechanical Characterization and Integration of One Dimensional Metallic Nanostructures
摘要:
One dimensional (1-D) metallic nanostructures (e.g. nanowires, nanorods) have stimulated great interest recently as important building blocks for future nanoscale electronic and electromechanical devices. In this work, gold and nickel nanowires with various diameters were successfully fabricated, and two dedicated platforms, based on (1) a novel micro mechanical device (MMD) assisted with a quantitative nanoindenter and (2) a TEM-AFM sample holder system, were developed and adopted to perform in situ tensile tests inside SEM and TEM on samples with diameter ranging from a few nanometers to hundreds nanometers. Size-dependent mechanical behavior and different fracture mechanisms of gold nanowires had been revealed and discussed. In addition, we discovered cold welding phenomenon for ultrathin gold nanowires (diameter < 10nm), which is anticipated to have potential applications in the future bottom-up integration of metallic 1-D nanostructures and next-generation interconnects for extremely dense logic circuits."
