Moore’s Law, which has long described the scaling evolution of electronic devices, is now approaching its limit, highlighting the constraints of CMOS technology under extreme miniaturization. The search for alternatives to silicon-based systems has therefore driven research toward new and more promising technologies, capable of complex computation with minimal size and power consumption. One of the most relevant beyond-CMOS approaches is Molecular Field-Coupled Nanocomputing (MolFCN). MolFCN encodes binary information by localizing charges within molecules organized on a substrate to form functional structures, such as wires. The initial MolFCN wire design, known as the trench device, features a core metallic layer hosting molecules deposited at the bottom of a dielectric trench, with two metal electrodes placed at the top of the trench walls.
