Postdoctoral Position
Cluster Beam Deposition/Monodisperse Supported and Embedded Cluster
Catalysts
A postdoctoral position is available immediately in the lab of
Scott Anderson at the University of Utah. The goal is to characterize
two types of model cluster catalysts, prepared by deposition of a
mass-selected cluster ion beam. Clusters are prepared in a 100 Hz
laser vaporization source, and are mass selected and deposited using
our phase-space compressed cluster ion beam line (Rev. Sci. Instrum,
69 (1998) 4106-15), which allows deposition at energies down to about
100 meV/atom. Supported model catalysts are prepared by depositing
mass-selected clusters ions on planar oxide film supports at very low
impact energies to minimize cluster breakup and substrate damage. By
studying effects of cluster size on physical and chemical properties,
we hope to better understand the origins of the size-dependent
chemistry found in ultra-disperse catalysts. At high deposition
energies, "embedded" model catalysts are produced, where the metal
cluster is embedded in the support material. These studies are aimed
at understanding effects of support structure/defects on catalytic
properties, and may possibly provide a mechanism for stabilizing
ultra-disperse catalysts against sintering. In addition to the 100 Hz
source/phase space compressing beamline, the instrument is equipped
for XPS, XAS, EELS, TPD, and STM. We plan to add TOF-SARS, AES, and
UPS/MIES during the next year. Additional information about the
project and other experiments in the Anderson group can be found at:

Experience with UHV/surface science is strongly preferred,
however, the most critical criterion is creativity. The initial
appointment will be for one year, with the expectation of renewal for
a second year contingent upon reasonable progress. Salary will be
competitive, and the position includes excellent health insurance.
Salt Lake is a great place to live, with world-class skiing, hiking,
