Robustness of the In-Plane Data Crossing for Molecular Field-Coupled Nanocomputing

Molecular Field-Coupled Nanocomputing (molFCN) offers several advantages compared to other beyond-CMOS technologies, such as the cut of the power dissipation, thanks to the absence of charge transport, and the possibility to work at room temperature. Several circuits have been investigated for molFCN, primarily analyzed from a behavioral standpoint. Also, researchers proposed a few solutions to cross two signals and analyzed them from a logical and ideal perspective. Crossing information is an essential and delicate operation since molFCN is an in-plane technology. Besides, previous works demonstrated the need to consider molecule physics to predict the behavior of a molFCN circuit. This work examines different implementations of the in-plane information crossing interconnection, considering the punctual molecule physics to predict the interconnection functioning. We tune the electrostatic feature of the involved molecules to determine the robustness of the cross-wire against static electrostatic variations, thus providing valuable information for the synthesis of ad-hoc molecules for molFCN.
