Kent Budd

Kent Budd, senior staff scientist, Corporate Research Materials Laboratory, 3M, USA


Title: EMA-related technologies and research at a diverse global manufacturer


Abstract: Woven into a fabric made up of office supplies, tape, and abrasives are several 3M Company products and technologies involving electronic materials and applications. Examples include composite capacitors, lithium ion battery components, and materials for high voltage power, communications, and displays. A career spent in 3M’s Corporate Research Labs has involved project experiences nearly as diverse and wide ranging as 3M itself. Selected topics and experiences are explored by building on some early projects, and tracing them forward to current products, research, and critical technology areas. Energy storage is discussed, with reference to high permittivity dielectrics, supercapacitors, and lithium ion battery components. A variety of electrical components are overviewed, including transparent conductors, high voltage transmission products, and EMI / EMC materials. Finally, materials for optical products and displays are described, including quantum dot light emitters, ultra high barrier film, and light management materials. Limitations, needs, and future directions are discussed in addition to current products and technologies.


Biography: Budd leads two technology platforms related to inorganic and ceramic materials. He received a B.S. and Ph.D. in Ceramic Science and Engineering from the University of Illinois, with research focused on chemical preparation of electrical ceramic thin films. Kent joined 3M in 1986, where he has worked primarily in corporate lab and technology center organizations. This path has led to interactions with many different 3M divisions, and to work on a diverse range of materials and technologies. The work has resulted in over 40 issued or pending U.S. patents and several commercialized products, including electroluminescent backlights, pavement marking materials, Er-doped optical fibers, embedded capacitors, and dental restoratives.


Greg Rohrer 

Greg Rohrer, W.W. Mullins Professor of Materials Science, head, Materials Science and Engineering Department, Carnegie Mellon University, USA


Title: High throughput, data rich experiments and their impact on ceramic science


Abstract: The automated control of materials characterization instruments and the digital storage of data have created new opportunities for ceramic science. Automated control makes it possible to record volumes of data that were not possible in the past and digital storage makes it possible to compare data in new and difficult to predict ways. This will be illustrated with two examples. First, I will describe combinatorial substrate epitaxy experiments to determine the orientation relationships between phases that result from thin film growth. Second, I will discuss three-dimensional orientation mapping experiments that provide a rich source of data on microstructures and grain boundaries. Finally, I will speculate on opportunities to advance ceramic science through the storage and curation of digital data.


Biography: Rohrer received his bachelor’s degree in Physics from Franklin and Marshall College in 1984 and his Ph.D. in materials science and engineering from the University of Pennsylvania in 1989. Rohrer is an Associate Editor of the Journal of the American Ceramic Society, was chair of the Basic Science Division of ACerS in 2005, and was chair of the University Materials Council in 2011. He has authored more than 230 publications and received a number of awards recognizing his research. From The American Ceramic Society, he has received the Roland B. Snow Award (1998), the Ross Coffin Purdy Award (2002), the Richard M. Fulrath Award (2004), the Robert B. Sosman Award (2009), and the W. David Kingery Award (2014).


Hiroshi Funakubo 

Hiroshi Funakubo, professor, Tokyo Institute of Technology, Japan


Title: Domain motion under applied electric field in Pb(Zr, Ti)O3 films and their contribution to the piezoelectric properties


Abstract: Piezoelectric films have been widely investigated for various applications. Due to the close correlation between the piezoelectric property and the crystal structure, crystal structure analyses have been carried out mainly for the as-deposited films. In addition, the crystal structure change under an applied electric field is known strongly affect to their piezoelectricity. Therefore, various methods have been applied to investigate the crystal structure change under applied an electric field. In the present study, we introduce the quantitative analysis of the crystal structure change under applied an electric field using in-situ Raman spectroscopy and XRD under applied an electric field. In addition, we also evaluate how fast the crystal structure changes under an applied electric field using time-resolved XRD measurement using Spring-8 synchrotron setup. The present results clearly indicate the impact of the evaluationnot only crystal structureof as -deposited films but also crystal structure change under an applied electric field to understand the piezoelectric properties of Pb(Zr, Ti)O3 films.


Biography: Funakubo is a professor in the department of innovative and engineered materials. He received the Ph.D. from Tokyo Institute of Technology. In 1989, he was an assistant professor in the faculty of engineering, Tokyo Institute of Technology. In 1997 and 2012, he has been an associate professor and full professor of interdisciplinary graduate school of science and technology, department of innovative and engineering materials, Tokyo Institute of Technology. Specific areas of interest include preparation and properties of dielectric, ferroelectric and piezoelectric films.
