Presentation Transcript

  1. Silicon Carbide Nanocones and HeterostructuresJudith C. Yang, University of Pittsburgh, DMR 0804892 Crystalline SiC Y junction Goal: An approach to produce 1-dimensional (1D) nano-structures is by metal-catalyzed nanowire formation via the vapor-liquid-solid mechanism. By en-capsulation and controlled release of the metal catalyst followed by agglomeration, the exposed surface area of the catalyst leads to the formation of unusual 1D nanostructures and hetero-structures, such as Y junctions. Outcome: Mechanistic understanding of the catalytic reaction governing 1D nanostructure and hetero-structure formations. Such knowledge is necessary for making nano-devices using 1D nanostructures with specific architectures and properties.

  2. Silicon Carbide Nanocones and HeterostructuresJudith C. Yang, University of Pittsburgh, DMR 0804892 Research Experience: Post-doctoral: This grant provides the support for one post-doctoral research associate: Dr. Zhenyu Liu High School Outreach: Figure: 2nd annual PJAS and PECAP “Visualization of Nanotechnololgy” workshop. U. Pittsburgh. 10/11/08 The PI participates in the annual Pennsylvania Junior Academy of Science (PJAS) workshop where local high school students visit the the Nanofacility at U. Pittsburgh for hands-on demonstrations for a day, including electron microscopy. The recent PJAS includes Pitt Engineering Career Access Program (PECAP) students. PECAP is a U. Pittsburgh program to recruit, retain and students from under-represented groups in the STEM fields. Undergraduate Research Experience: This grant provides the support one female undergraduate student for summer research projec on C nanotubes: Ms. Kelsey Finegan (5/09- 8/09) Kelsey Finegan Zhenyu Liu
