Molecular circuit design

Abstract

With a more realistic vision of a possible limit for miniaturization of components with conventional CMOS technology, a new technology has surfaced -molecular electronics which, from the bottom-up approach, aims at the construction of electrical devices to implement computation using individual or small collections of molecules, offering an alternative way to build nanoscale circuits. These circuits have the potential to reduce device size and fabrication costs by several orders of magnitude relative to conventional CMOS. Recently, some mechanisms have been considered as a basis to molecular electronic systems design. Two terminal molecular devices that work as diodes have been synthesized, with similar behavior to rectifying and tunnel diodes. In this article, a study on the synthesis of molecular circuits is presented, integrating simulated molecular devices as the molecular Tour-Reed diode based on the evolvable hardware (EHW) paradigm.
