Designing and Modeling of Logic Circuits Based on Switching of the Gated Oligo-Phenylenevinylene Molecule

摘要

Molecular electronics seeks to decrease the cost, power consumption and size of devices, using a variety of approaches. However, few attempts have been made to address circuit simulation. The availability of common semiconductor components means they can be used for modeling and simulating molecular circuits to speed progress in molecular electronics. The present study examines the switching of a gated oligo-phenylenevinylene (OPV) molecule as a NMOS molecular transistor, resistance as an indicator of methyl molecules, and the linking of these abilities using LTspice simulation software. The circuit simulation of molecules of basic logic gates, half-adder, full-adder, and multiplier logic circuits are carried out. The numerical results may shed light on the next applications of molecular systems and make them a good, promising candidate for field-effect transistors.
