A bi-weekly event to present and discuss issues related to developments, applications and commercialization of nanotechnology.

Electronic-Grade Carbon Nanotube Solutions

(VIDEO CONFERENCED FROM THE AUSTIN OFFICE OF Winstead PC)

Abstract: Brewer 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/(Vs), high current-carrying capacity > 30 mA, 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 thin-film transistors, 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.
