Abstract
Molecular electronics (sometimes called moletronics) involves the study and application of molecular building blocks for the fabrication of electronic components. This includes both passive and active electronic components. Molecular electronics is a branch of nanotechnology. An interdisciplinary pursuit, molecular electronics spans physics, chemistry, and materials science. The unifying feature is the use of molecular building blocks for the fabrication of electronic components. This includes both passive (e.g. resistive wires) and active components such as transistors and molecular-scale switches. Due to the prospect of size reduction in electronics offered by molecular-level control of properties, molecular electronics has aroused much excitement both in science fiction and among scientists. Molecular electronics provides means to extend Moore's Law beyond the foreseen limits of small-scale conventional silicon integrated circuits. Molecular electronics is split into two related but separate subdisciplines: molecular materials for electronics utilizes the properties of the molecules to affect the bulk properties of a material, while molecular scale electronics focuses on single-molecule applications. Concept genesis and theory In their 1940's discussion of so-called "donor-acceptor" complexes, Robert Mulliken and Albert Szent-Gyorgi advanced the concept of charge transfer in molecules. They further refined the study of both charge transfer and energy transfer in molecules. Likewise, a 1974 paper from Mark Ratner and Ari Aviram illustrated a theoretical molecular rectifier. In 1988, Aviram described in detail a theoretical single molecule field-effect transistor. Further concepts were proposed by Forrest Carter of the Naval Research Laboratory, including single-molecule logic gates. These were all theoretical constructs and not concrete devices. The direct measurement of the electronic characteristics of individual molecules awaited the development of methods for making molecular-scale electrical contacts. This was no easy task. Thus, the first experiment directly-measuring the conductance of a single molecule was only reported in 1997 by Mark Reed and co-workers.
