Scientific Issues with Carbon Nanotube Transistors
University of Montreal
Electroactive molecules and molecular nanostructures are explored intensively as new alternative materials for electronic applications. Among the most promising systems for molecular electronics, the single-wall carbon nanotubes (CNs) are particularly interesting. These long cylindrical nanostructures involve covalent bonds, which make them exceptionally strong. Moreover, they offer excellent conduction and high current carrying capabilities. I will quickly review their electrical properties and show the recent progress for building carbon nanotube field-effect transistors (CNFETs). We will also present physical and chemical phenomena occurring at the metal-nanotube junctions. Finally, I will present the smallest light source based on a CNFET with an emission wavelength in the near IR region.
