Controlling molecular electronics with rigid, ladder-like molecules

As electronic devices continue to get smaller and smaller, physical size limitations are beginning to disrupt the trend of doubling transistor density on silicon-based microchips approximately every two years according to Moore's law. Molecular electronics -- the use of single molecules as the building blocks for electronic components -- offers a potential pathway for the continued miniaturization of small-scale electronic devices. Devices that utilize molecular electronics require precise control over the flow of electrical current. However, the dynamic nature of these single molecule components affects device performance and impacts reproducibility.
