UI researcher receives $240,000 NSF research grant
IOWA CITY, Iowa -- A University of Iowa researcher has received a three-year,
$240,000 grant from the National Science Foundation (NSF) for a theoretical
study of novel semiconductor devices.
Michael Flatté, professor in the College of Liberal Arts department
of physics and astronomy and researcher in the UI Optical Science and Technology
Center, will conduct the study in collaboration with the University of Illinois
at Chicago and HRL Laboratories in Malibu, Calif. The work will be directed
toward the design of such devices as intense infrared lasers and sensitive
infrared detectors for biomedical and communications applications.
Flatté says that advances in these novel devices require advances
in the understanding of "nanostructured semiconductor materials,"
which are artificially constructed, microscopic materials typically thinner
than seven atoms wide in at least one direction. He notes that results from
this theoretical work will complement ongoing efforts within the Optical Science
and Technology Center to develop novel semiconductor materials for optical
devices that are customized for noninvasive blood glucose sensing, real-time
monitoring of fuel cell engines, and high-bandwidth wireless technology. The
research will be conducted in the Iowa Advanced Technology Laboratories Building
on the UI campus.
Earlier this year, Flatté and Thomas Boggess, professor of physics
and astronomy in the College of Liberal Arts and professor of electrical and
computer engineering in the College of Engineering, received a two-year, $301,000
grant from the U.S. Air Force Research Laboratories to study materials currently
used in biomedical and air pollution monitoring devices. Their work may become
the foundation of the next generation of electronic devices for high-speed
information processing. Flatté also received $30,000 from the U.S.
Air Force to aid in the application of these materials to energy collection
processes in power plants.
Boggess and Flatté, along with other UI faculty, previously collaborated
in the development of a long-wavelength, infrared semiconductor laser that
may be useful in non-invasive biomedical monitoring.
