文摘

Molecular electronics technology removes limitations on miniaturization of semiconductor-based devices. With shrinking device sizes, we can expect smaller but more efficient devices. This branch of research also speeds up the devices, which enables us to have faster processors in the future. In order to have progress in this branch of research, we need to have modeling based on realities. Due to the availability of semiconductor-based devices, they can be used to further the goals of modeling in this field. Here, a specific procedure for the design and modeling of the molecular logic circuit based on the transistor structures is provided. That is, we use the circuit modelling for a gated oligo-phenylene vinylene (OPV) molecule as a NMOS molecular transistor’s swithch and a methyl molecule as a resistor. We also benefited from the capabilities of the LTspice simulator software. Connecting these components, we could successfully conduct the circuit simulation of the combinational logic circuits, such as decoder, encoder, multiplexer, and comparator logical molecules, and prove the validity of the model.
