Synthesis and assembly roadblocks to nanotube and graphene electronics
Semiconducting carbon nanotubes and graphene nanoribbons have massive potential in future high-performance semiconductor electronics. However, they have been held back by major roadblocks in synthesis and assembly. This seminar will present recent advances in (1) the self-assembly of semiconducting carbon nanotubes into dense arrays like those needed for microelectronics, via two-dimensional liquid-crystalline interactions at fluid-fluid interfaces1; (2) the bottom-up anisotropic synthesis of semiconducting graphene nanoribbons on Ge and Ge on Si substrates via CVD of polycyclic aromatic hydrocarbon molecular seeds and methane2; and, (3) structure-electronic properties relationships of these materials. The application of atomically thin materials with faceted edges to direct the self-assembly of block copolymers via a new mechanism called boundary-directed epitaxy3 will also briefly be introduced.
Presented by Professor Michael Arnold, University of Wisconsin
Michael S. Arnold is a Professor of Materials Science and Engineering at the University of Wisconsin-Madison. He earned a B.S. in Electrical and Computer Engineering at the University of Illinois, Urbana-Champaign before completing a Ph.D. in Materials Science and Engineering at Northwestern University and postdoctoral research in Electrical Engineering and Physics at the University of Michigan, Ann Arbor. His research interests include all things carbon nanotubes and graphene, from novel synthesis techniques to fabrication of next-generation nanoelectronics. In his free time, he enjoys running, mountain biking, tennis, eating Babcock Dairy quadruple scoops, and spending time with his family.
