ABSTRACT:
A digital inverter formed by three carbon nanotubes (CNTs) extending vertically from a substrate, one CNT functioning as first source (S1) and having a first logic signal applied to it, another CNT functioning as second source (S2) and having a second logic signal applied to it, a third CNT functioning as gate (G), and disposed between the two sources (S1, S2). A drain (D) contact is associated with the gate (G). A logic signal applied to the gate (G) causes one or the other of the sources (S1, S2) to deflect, contacting the drain (D) and transferring its logic signal thereto—such as logic “0” on the gate resulting in logic “1” (from one of the sources) being transferred to the drain (D), and logic “1” on the gate resulting in logic “0” (from the other of the sources) being transferred to the drain (D).
