This is an abstract for a presentation given at the
Ninth Foresight Conference on Molecular Nanotechnology.

The speaker will describe novel designs and experiments for producing signal amplification or "gain" using only demonstrated two-terminal molecular diodes. This addresses one of the most challenging and important problems in molecular-scale electronics, since gain-producing devices are essential for the implementation of extended computer architectures [1]. Moreover, using molecular diodes, the designs described here circumvent the difficulties inherent in fabricating a three-terminal molecular device analogous to a transistor, which is used to achieve gain in conventional micron-scale computer circuits. This is especially important because most of the molecular switches that have been demonstrated to date are diodes. In this connection, the speaker will discuss requirements for molecular-scale gain producing elements that employ diodes and the prospective application of these elements for the implementation of extended molecular circuitry.
