Chemically Functionalized Carbon Nanotubes for Microelectronics Applications
Christopher Smart (Chemistry)
We are interested in the chemical functionalization of carbon nanotubes, to create materials with new properties that may have applications in nanotechnology. Examples of such materials would be novel chemical sensing agents, materials with improved capacitance or conductivity for microchip components, or novel redox systems for battery applications. We prepare nanotube thin films by chemical vapor deposition and functionalize them via a variety of electro-chemical processes. The nanotube films are analyzed by scanning electron microscopy, Raman spectroscopy, and elemental analysis, and are also characterized electrochemically. In addition, the chemical vapor deposition process will be monitored in situ by mass spectrometry. We will investigate and compare the growth of carbon nanotubes on a variety of substrates including silicon wafers coated with nickel silicide, silicon wafers ion-implanted with cobalt, and gold mesh substrates.
Pre-requisites: Chemistry 108/108 or the equivalent (including lab) and Chemistry 244/245 or the equivalent (including lab) should provide adequate lab skills for this project.
How should students express their interest in this project? I would like to have a short interview (20 minutes) with anyone interested in this project. Students interested in this project do not need to do anything to prepare for this interview.
