Overcoming Junction Resistances in Carbonaceous Conductors
Abstract
The goal of this project is to significantly increase the conductivity of yarns made from carbon nanotubes (CNTs) through the integration of state-of-the-art atomistic simulations and a series of advanced processes. Specifically, this project aims to address the issue of internal junction resistances, which is thought to be the main obstacle for achieving extremely high conductivity in carbonaceous conductors. By eliminating semiconducting CNTs and proper doping of the resulting yarns with potent intercalants, it is hypothesized that superior conductivities can be achieved. This project will use atomistic simulations to design both nanotube junctions and processes that can achieve them. Finally, the project will study the impact of advanced conductor materials on the performance and cost of various naval power and energy systems, with the aim of identifying energy and cost efficient, lightweight, and durable alternatives to copper for use in the US Navy.
