Abstract:
1. A nanotube transistor comprising: a source and drain; a metal gate electrode; a channel between the gate electrode and the source and drain formed of at least two nanotubes; and a pair of V-shaped trenches formed in a semiconductor substrate, each of said trenches including one nanotube, said V-shaped trenches having walls that are lined by an insulating material, said V-shaped trenches having a width approximately twice the diameter of said nanotubes, said V-shaped trenches are lined with a dielectric layer having a dielectric constant greater than ten, wherein said V-shaped trenches include a dielectric material formed in said V-shaped trenches over said nanotubes, said metal gate electrode extending into said V-shaped trenches.
