Keynote: Building and Engineering Highly Organized Single-walled Carbon Nanotube Network Architectures for Various Sensor Applications
Time : 09:15-10:00
Dr. Yung Joon Jung is Professor at Northeastern University, Department of Mechanical and Industrial Engineering and co-faculty director at Kostas Advanced Nano Characterization Center at Kostas Research Institute, Northeastern University. He received Ph.D. in Materials Engineering from Rensselaer Polytechnic Institute, 2003. He worked as a Postdoctoral Fellow at Rensselaer, and joined Northeastern University at 2005. Prof. Jung’s research focuses on investigating new synthetic routes for low dimensional nanomaterials and engineering their molecular structures. He also develops nanomanufacturing processes such as assembly and integration of nanomaterials and nanostructured architectures for nanoelectronics, flexible devices, various sensors and energy storage applications supported by National Science Foundation, Department of Defense, US Army, Ministry of Industry in Republic of Korea and other industries. He published over 65 articles in journals and three book chapters. He is also a co-founder of Guradion Technologies that develop networkable high performance ion and radiation sensors.
Over the past two decades, researches on low-dimensional carbon nanostructured materials (SWCNT and graphene) designed for a variety of sensor applications have made remarkable progress. However scalable fabrication and engineering of high performance sensors that harness 2-3 dimensional nano/micro architectures of these nanomaterials have remained largely elusive. Such methodologies will allow unprecedented device architectures fully utilizing superior physical and chemical properties of these nanomaterials for high performance and low SWaP sensors. Here we present some of our progresses in assembly and engineering of singlewalled nanotube networks and building 2-3D architectures for broad ranges of high performance chemical, optical and ion sensors by combining state-of-the-art assembly and transfer based nanomanufacturing strategies developed in our laboratory.

Tohoku University, Japan
Time : 11:15-12:00
Masumi Saka has received his Bachelor of Engineering degree in 1977 and his Doctor of Engineering degree in Mechanical Engineering in 1982, both from Tohoku University, Sendai, Japan. He became a Professor at Tohoku University in 1993. His research interests lie in the evaluation of materials system and the fabrication of metallic micro- and nano-materials. He is an Editor of a book entitled “Metallic Micro and Nano Materials”.
Migration phenomena of atoms and ions have been known as negative factors, resulting in the deterioration in the electronic devices through the formation of voids, hillocks, whiskers and dendrites. For instance, the electromigration (EM), stress-induced migration (SM) and Electrochemical Migration (ECM) are owing to driving forces of electron flow, mechanical stress gradient and electric field, respectively. EM forms voids and hillocks at the ends of cathode and anode in interconnect. SM generates hillocks and whiskers in the thin films and interconnects. ECM precipitates the dendrites with fractal shape in water and on the surface of electrode. These migrations have often been studied on Al, Sn and Cu elements which are widely used as interconnects in devices and several countermeasures were proposed to improve the reliability of devices. Recently, the fabrication techniques of micro/nano materials have been developed by applying the scientific knowledge obtained from the prevention researches. Micro/nano materials with shapes of wire, rod, tube and needle are promising materials for enhancing the device performance. The trial fabrication and synthesis techniques have been demonstrated to grow upcoming materials. In particular, our group has developed the fabrication techniques of micro/nano materials by using EM, SM and ECM. In this presentation, our trials of the fabrication techniques are reviewed for getting an insight into advanced fabrication and application of the materials.
