Charge-based re-programmable logic device with built-in memory: New era in molecular electronics

摘要

We put forward a new proposal of designing charge-based logic devices considering a cyclic molecule that can be programmed and re-programmed for different functional logical operations and suitably engineered for data storage as well. The key idea is based on the appearance of bias induced circular current under asymmetric molecule-to-electrode interface configuration which does not dissipate even when the bias is off. Our results are valid for a broad range of parameter values, and provide a boost in the field of storage mechanism, reconfigurable computing, charge-based logic functions and other nano-scale applications.
