Abstract

In recent years, several experimental groups have reported measurements of the current-voltage (I-V) characteristics of individual or small numbers of molecules. Even three-terminal measurements showing evidence of transistor action has been reported using carbon nanotubes as well as self-assembled monolayers of conjugated polymers. These developments have attracted much attention from the semiconductor industry who are actively looking for ways to progress from gigabit to terabit integration by complementing or even replacing presentday CMOS circuitry.
