Toward 100% Semiconducting Devices From Mixed Chirality Nanotube Networks

Young-Kyun Kwon, Physics

Novel modeling techniques are used to characterize the structural, electronic and optical properties of nanocomposite network semiconductors. Ab initio computations of the structural properties of ensembles of nanotubes on a variety of substrates are presented. Thi project used Monte Carlo and percolation simulations to predict manufacturing success rates given semiconductor design and processing constraints. The performance impact of flattening of nanotubes and topological defects on nanotubes also was presented. The purpose of this study is to assist experimentalists and to stream-line and optimize nanomanufacturing.

This research focuses on the fundamental understanding of nanostructured materials and their application to molecular electronic devices.
