Colloquium Date: Monday, February 19, 2007
A bi-weekly event to present and discuss issues related to developments, applications and commercialization of nanotechnology.
Electronic-Grade Carbon Nanotube Solutions
Speakers: Xuliang Han, Ph.D.
(VIDEO CONFERENCED FROM THE AUSTIN OFFICE OF Winstead PC)
Science, Inc. is currently producing unique electronic-grade carbon
nanotube (CNT) solutions. The proprietary technique can effectively
remove both metallic and carbonaceous impurities in the raw soot, and
the outcome is a stable solution that contains individually suspended
ultrapure CNTs without any surfactant. With these unique
electronic-grade CNT solutions, a number of
solution-casting processes, such as spin coating,
spray coating, and micro dispensing, have been
successfully demonstrated to form ultrapure CNT
films of various densities. These ultrapure CNT thin
films can function as excellent carrier transport
layers in thin-film transistors (TFTs). A CNT-TFT
has been fabricated on a regular transparency film
with extraordinary field-effect mobility ~48,000
cm2/(Vs), high current-carrying capacity >
and high modulation speed >300 MHz. Other
applications of these unique electronic-grade CNT
solutions will also be discussed.
Bio: Dr. Xuliang Han received his Ph.D. in
Electrical and Computer Engineering from The
University of Texas at Austin in 2003. In his Ph.D.
research, he invented optical centralized shared bus
architecture, implemented the first fan-out
equalized optical backplane bus, and demonstrated
centralized microprocessor-to-memory optical
interconnects at 1.25Gbps on a prototype machine.
After graduation he joined Brewer Science, Inc. as a
Senior Research Engineer. Currently he is developing
carbon nanotube based electronic devices, such as
infrared sensors, and biosensors. He is also
investigating the basic properties of nanomaterials
by using various optical spectroscopic techniques,
such as Raman and spectrofluorescence.
Dr. Han is an adjunct faculty member at
Missouri State University, and a member of IEEE,
SPIE, and MRS.
