Abstract

We present the first-principles calculation of transport properties of a semiconducting carbon nanotube connected to aluminum metallic electrodes. The transmission spectrum of the nanotube shows a decrease in the band-gap energy level but has a finite value due to the hybridization of the metallic states of the electrodes.
