Seidman Recognized for his Career Contributions to Materials Science

March 26, 2009 | by Megan Fellman
EVANSTON, Ill. --- David Seidman, Walter P. Murphy Professor of Materials Science and Engineering at the McCormick School of Engineering and Applied Science at Northwestern University, was selected as the Materials Research Society's 2008 Turnbull Lecturer.

The Turnbull Lecturer Award recognizes the career of a scientist who has made outstanding contributions to understanding materials phenomena and properties through research, writing and lecturing, as exemplified by the late American materials scientist David Turnbull of Harvard University. This award is the second-highest award made by the Materials Research Society (MRS) annually.

Seidman received the award "for research that has made major contributions to our understanding of point defects and the role they play in radiation damage and phase transformations; unique studies of interfacial segregation; and especially for the development and fruitful use of atom-probe spectrometry; for numerous seminal publications, and excellence in education/training students and colleagues in the laboratory, classroom and conferences."

Seidman delivered his Turnbull Lecture, titled "On the Genesis of Nuclei and Phase Decomposition on an Atomic Scale," at the MRS fall meeting in December 2008.

His research aims to understand physical phenomena in a wide range of material systems on an atomic scale. Currently he and his research group are studying aluminum-, nickel- and iron-based alloys for possible high-temperature and structural applications, and metal silicide/silicon reactions pertinent to solid-state devices.

Seidman and his research group utilize highly sophisticated microscopy and spectroscopy instrumentation (3-D atom-probe tomography, transmission electron and scanning electron microscopies) to study interfaces on a subnanoscale level. They also perform simulations using lattice-kinetic Monte Carlo, local-density functional theory and lattice statics simulations in parallel with the experiments to help interpret the experimental results at an atomic level.

Seidman heads the Northwestern University Center for Atom-Probe Tomography (NUCAPT), the second-largest atom-probe tomography group in the world, housed in William A. and Gayle Cook Hall on the Evanston campus.
