| 报告介绍 | Throughout the history of mankind, scientists and engineers have relied on the slow and serendipitous trial-and-error approach for materials discovery. In 1990s, the combinatorial approach was pioneered in the pharmaceutical industry in order to dramatically increase the rate at which new chemicals are identified. The high-throughput concept is now widely implemented in a variety of fields in materials science. We have developed combinatorial thin film synthesis and characterization techniques in order to perform rapid survey of previously unexplored materials phase space in search of new inorganic functional materials. Various thin film deposition schemes including pulsed laser deposition, electron-beam deposition, and co-sputtering are implemented for fabricating massive arrays of compositionally varying samples on individual combinatorial libraries. A suite of high-throughput characterization tools are employed to screen the combinatorial libraries and map different physical properties of materials as a function of sweeping composition changes. They include scanning x-ray microdiffraction, room-temperature scanning SQUID microscopy, microwave microscopy, and micromachined MEMS cantilever arrays. In addition to the composition space, the approach can be also used to address other parameter spaces such as film thickness, interface layers, etc. which can control the overall materials performance. The people: Ichiro Takeuchi is a professor in the Department of Materials Science and Engineering at the University of Maryland. His research interests include novel multilayer thin-film devices, scanning probe microscopes, and development of combinatorial materials science methodology. He received his BS degree in physics from California Institute of Technology in 1987 and PhD degree in physics from the University of Maryland in 1996. He was a postdoctoral research fellow at Lawrence Berkeley National Laboratory from 1996 to 1999. He received the Office of Naval Research Young Investigator Award in 2000 and the National Science Foundation's CAREER Award in 2001. Takeuchi is a fellow of the American Physical Society. |
