Moletronics modeling toward molecular potentials

摘要

Using ab initio density functional theory (DFT) calculations, we demonstrate two molecular OR gates that are able to process binary signals encoded as molecular potentials. Thus, the possibility to implement logic gates of < 1 nm is demonstrated. The advantage of this approach to post-microelectronics technologies is the tremendous low-power dissipation, the small feature size of molecular devices, and the compatible nature of input and output signals that would allow the implementation of complex logic.
