Carbon Nanotube Growth and Sensor Application
We have grown carbon nanotubes using standard chemical vapor deposition (CVD) and plasma enhanced chemical vapor deposition (PECVD). This is a collaborative effort with a PECVD system in the lab of Dr. Rudy Schlaf of the USF Electrical Engineering Department, the CVD tube furnace in the lab of Dr. Eric Snow at NRL-Washington D.C., and our own CVD tube furnace that was co-purchased by our lab and the lab of Dr. Garrett Matthews in our Physics Department. Here are some SEM and TEM images of nanotube grown in the three different systems:
These nanotube networks are the basis for biological and chemical sensors that sensitively measure changes in capacitance and conductance when analyte molecules adsorb onto the surface of the network.
