Abstract:
1. A method of making a transistor device comprising: anodizing an aluminum substrate to produce an alumina template with a plurality of pores, each having a pore diameter; exposing the template having pores to a hydrocarbon gas at a temperature to grow carbon nanotubes in the pores, each carbon nanotube having an outer diameter less than the pore diameter in the template in which the carbon nanotube is produced; forming a first electrode region to electrically couple to first ends of the carbon nanotubes; forming a second electrode region to electrically couple to second ends of the carbon nanotubes; forming first and second trenches in the template; forming an insulator layer in the first and second trenches; forming a first gate electrode on the insulator layer in the first trench; and forming a second gate electrode on the insulator layer in the second trench, wherein between the first and second gate electrodes are at least two carbon nanotubes in the template.
