Exploration of Highly-Ordered Carbon Nanotube Arrays for Infrared Detection
Abstract
During the course of this project, we employed and extended our unique capability in template-growth of nanostructured materials, particularly carbon nanotubes. This fabrication capability formed the foundation for farther investigations, into the infra-red properties and transport properties of these nanostructures. We were able to fabricate large arrays of identical carbon nanotubes with identical properties, which enabled sufficient signal enhancement to perform novel infra-red spectroscopy studies on the nanotubes. Extensions of our core fabrication method enabled the creation of carbon nanotube arrays on silicon wafers. The importance of silicon as a semiconductor material cannot be overstated, and so the fabrication and measurements of these structures represents an important step toward integrated Si-CNT infrared detectors. The results of this project clearly demonstrate the feasibility of employing ordered carbon nanotube arrays in infra-red detection applications.
