Carbon-Based Avalanche Devices for Low-Power Electronics.

摘要

This report summarizes our 3-year efforts in understanding operation and reliability of graphene transistors and interconnects supported by this AFOSR-YIP award. The core of the graduate student team has been Enrique Carrion (an underrepresented minority student), who has done excellent work and who will soon complete his PhD. Enrique has recently completed a study of top-gated graphene transistors, including their variability and other real world challenges. A junior student (Ning Wang) has been leading our work on carbon nanotubes (CNTs), including extensive modeling and fabrication of avalanche- induced switching in CNT transistors. More details can be found in the submitted PDF file, including all publications, conference proceedings, and invited talks supported in full or in part by this grant. Importantly, a major review paper on 'Thermal Properties of Graphene: Fundamentals and Applications was co-authored by the PI together with AFRL researchers A. Roy and V. Varshney, and published in MRS Bulletin, Dec 2012 issue. This collaboration with AFRL would not have been possible without this AFOSR-YIP grant. The PI also visited AFRL (WP-AFB) and hosted AFRL researchers at UIUC twice during the duration of this grant.
