Grants and Contracts Details
A novel approach to the molecular electronic device applications based on carbon nanotubes is proposed which, if realized, will have important industrial applications. The theoretical methods involve large scale simulations using accurate quantum tight-binding molecular dynamics scheme as well as accurate quantum conductivity formalisms developed by the PI and co-workers. Simulation results can be used as a guide in the experimental investigations. The proposal aims to provide useful theoretical results for guiding the experimentally feasible elements of nanotube based electronics through the following: . Characterization ofresponse and I/O (input-output) to the outside world through metal contacts. . Nanotube multi-terminal junctions through metal-catalyzed nano-spot "welding" approaches using metal "glue". . Nanoelectronics of Metal Tips on Carbon Nanotubes. The proposal falls under the following focus areas of the Army research objectives: A robust electronics technology involving wider bandwidth, improved spatial resolution and compactness. These applications include the use of fundamental interactions at the molecular level for characterizing electrical systems. The technical challenge is to develop a robust electronic circuitry which should also be compact and cost effective, requiring new innovations in the area of nanoelectronics. This research area emphasizes efforts to establish a new and comprehensive base of knowledge for the electronic properties of solidstate materials, structures and devices.
