A major focus of David's research has been developing electron energy loss spectroscopy
as a quantitative tool for predicting materials properties. His work has demonstrated how
electronic-structure changes on the atomic scale can control the macroscopic behavior of systems
as diverse as turbine blades or transistors. He joined the
Applied and Engineering Physics faculty
at Cornell University in July 2003, is a graduate of the University of Sydney and completed his Ph.D.
in physics at Cornell in 1996. David was a member of the technical staff at Bell Laboratories from
1997 to 2003, where he applied his research on imaging single atoms and atomic-scale spectroscopy
to determine the physical limits on how small a transistor can be made. For this work, he was named one of
the top 100 young innovators in 2003 by Tech Review Magazine, and recipient of the Burton Medal
from the Microscopy Society of America in 2006.
He has 5 patents and has published over 80 papers, including 12 in Nature or Science.
His work has received over 3000 citations.

John L. Grazul received his B.S. from Delaware
Valley College in 1984. From 1984 until 1999 he was technical
supervisor of the Bureau of Biological Research Electron Imaging
Facility at Rutgers University. There he was involved with biological
and materials research projects involving TEM, SEM, various cryo
techniques and sample preparation. He also was in charge of maintaining
all of the equipment and teaching. From 1999 until 2003 he was an MTS
at Bell Laboratories, Lucent Technologies working with Dr. Muller on
his various research projects involving high resolution STEM and TEM
room design. While at Bell Labs, John taught a class in Biological
Electron Microscopy at New Jersey City University. Currently, John is
manager of the TEM laboratory for the Cornell Center for Materials
Research.

I obtained my Bachelors of Science from the Department of Applied and Engineering Physics at Cornell University after also completing internships with the NNIN and Sandia National Laboratories . The overarching goal of my research is a microscopic understanding of the bulk and interfacial properties of copper wire barrier materials for improvements in barrier thickness and adhesion. This interface has proven a major source of failure in integrated circuits affecting the yield and lifetime of modern computer chips. I use a STEM optimized for EELS and electron tomography. EELS allows spatially resolved measurements of a material's local chemistry and electronic structure with atomic accuracy. Electron tomography is a technique to reconstruct 3D structures from a series of 2D images thus allowing quantitative investigation of buried features, such as barrier layer thicknesses and voids.

I obtained my undergraduate degree, Bachelor of Applied Science, from Simon Fraser University which is located at Burnaby, BC in Canada in 2003. Lured by the idea that a graduate student life will be relaxing, I came to Cornell to pursue a Ph.D degree in the department of Applied Physics. There are two research projects that I am currently working on. The first project is studying metallurgical contacts and interfaces in nanodevices using STEMs, EELS, and electron tomography. Currently I am focusing my attention on different adatoms on single-walled carbon nanotubes. 3D reconstruction of the adatoms on the carbon nanotubes via electron tomography will be used to investigate their physical structures and interfacial geometries. Furthermore, the local anisotropic chemical bondings between the adatoms and the carbon nanotubes will be probed with EELS. The second project is invesitigating the channeling and beam broadening effects inside solids as an electron beam passes through the zone-axis oriented solids. Studying these effects is cruicial as they might be a theoretical limiting factor in acheiving high resolutions in STEM. Office: E13 Clark Hall Phone: 607-255-0654 Email: |
