Patent ID: 8120008

Claim:
A carbon nano-tube based photoelectric integrated circuit, comprising: a substrate; a first high work-function electrode having a first work function and over the substrate; a second high work-function electrode having a second work function and over the substrate; a first low work-function electrode having a third work function and over the substrate; a second low work-function electrode having a fourth work function and over the substrate; a first carbon nanotube (CNT) over the substrate, wherein the first CNT forms a conductive channel between the first high work-function electrode and the second high work-function electrode; a second CNT over the substrate, wherein the second CNT forms a conductive channel between the second high work-function electrode and the first low work-function electrode; a third CNT over the substrate, wherein the third CNT forms a conductive channel between the first low work-function electrode and the second low work-function electrode, wherein the first work function and the second work function are higher than a work function of at least one of the first CNT, the second CNT, or the third CNT, wherein the third work function and the fourth work function are lower than a work function of at least one of the first CNT, the second CNT, or the third CNT; a dielectric material formed on the first CNT, the second CNT and the third CNT; and a conductive material in contact with the dielectric material.
