Molecular Electronics


Molecular electronics describes the field in which molecules are utilized as the active (switching, sensing, etc.) or passive (current rectifiers, surface passivants) elements in electronic devices. This review focuses on experimental aspects of molecular electronics that researchers have elucidated over the past decade or so and that relate to the fabrication of molecular electronic devices in which the molecular components are readily distinguished within the electronic properties of the device. Materials, fabrication methods, and methods for characterizing electrode materials, molecular monolayers, and molecule/electrode interfaces are discussed. A particular focus is on devices in which the molecules or molecular monolayer are sandwiched between two immobile electrodes. Four specific examples of such devices, in which the electron transport characteristics reflect distinctly molecular properties, are discussed.

© 2009 by Annual Reviews. First published online as a Review in Advance on April 28, 2009. Much of my thinking in the field of molecular electronics was heavily influenced by a tremendous set of UCLA and Caltech graduate students and postdocs, as well as treasured colleagues such as Sir Fraser Stoddart, Stan Williams, Philip Kuekes, and Bill Goddard. My own work described in this review was funded primarily through DARPA, the National Science Foundation, or the MARCO Center for Advanced Materials and Devices.
