报告内容简介：

With the development of nanotechnology, the measurement of electrical properties in local areas of materials and devices has become a necessity. Although many kinds of scanning probe microscopes have been developed to satisfy the demands of nanotechnology, a microscope technique that can determine the electrical properties in a local area is still under development. Recently, we proposed a microwave atomic force microscope (M-AFM) that is expected to be able to evaluate a material’s electrical properties, such as conductivity, permittivity and permeability; furthermore, this technique can measure the topography of a material on the scale of a nanometer. In this seminar, the development of the M-AFM and other research topics in our Lab. will be introduced.

His research interests are measurement and evaluation of mechanical and electrical properties of materials at micro- and nanoscale, utilizing microwave, THz wave, and femtosecond laser techniques, and regulation of mechanical and electrical stimulations on proliferation and differentiation of mesenchymal stem cells. He received the Japan Society of Mechanical Engineers Medal in 2006, the Best Paper Awards from the Japanese Society for Non-Destructive Inspection in 2002, and some other awards on sensing and evaluation of materials.

报告II题目: Formation of Metallic Micro/Nanomaterials by Utilizing Migration Phenomena and Techniques for Their Applications

 报告人: Masumi SAKA（坂 真澄）教授，Department of Nanomechanics，Tohoku University（东北大学），Sendai，Japan

报告内容简介：

Migration of atoms is presented to be utilized for fabrication of metallic micro/nanomaterials by controlling the phenomenon. Two kinds of migration phenomena are treated; one is electromigration and the other is stress migration. In addition to the formation of micro/nanomaterials, some achievements in enhancing their functions are demonstrated. One is a technique to fabricate nanocoils from the formed Cu nanowires.  The others are techniques to weld or cut the micro/nanowires by using Joule heating. Finally, regarding evaluation of mechanical and electrical properties of the micro/nanomaterials, the concentrated-mass cantilever technique in atomic force acoustic microscopy and the four-point atomic force microscope technique are shown to be powerful tools, respectively.
