The goal of this research program, funded under the auspices of the DARPA Moletronics program, is to fabricate a logic device less than 50 nm on a side, with associated input and output structures. The logic device we have chosen is a majority gate, so named because it compares three binary input signals and sends an output that corresponds to the most common input. In order to achieve this tiny size, the majority gate will be constructed from molecular components. Its principles of operation will rely on Coulomb interactions between these molecular components, rather than on flow of current or transistor function.
