Abstract Submitted to the    NANOTUBE'04 Conference:

An overview of our research efforts on chemical vapor deposition (CVD) grown carbon nanotubes will be presented. The discussion includes the controlled synthesis of single walled carbon nanotubes and small diameter few walled carbon nanotubes (FWNTs) as well as application development using the materials. More specifically, it includes the growth of long and well aligned single walled nanotubes; the fabrication of electronic devices and sensors using the aligned nanotubes; the effect of surface charges on the device characteristics of nanotube field effect transistors; the synthesis of small diameter FWNTs and the development of field emission devices using these materials.
