Abstract
Molecular electronics is difficult to fabricate with precise
positioning of large numbers of devices and their connections.
Self-assembly techniques can create such circuits but with some
random variation in their connection and characteristics. We show
such randomness can nevertheless produce reliable circuits by
adding enough redundant components to pass a sharp threshold in
likely circuit correctness. As an example of this approach, we
examine a demultiplexer circuit, useful for connecting nanoscale
circuits with larger conventional circuits.
