Programmable Molecular-Nanoparticle Multi-junction Networks for Logic Operations

We propose and investigate a nanoscale multi-junction network architecture that can be configured on-flight to perform Boolean logic functions at room temperature. The device exploits the electronic properties of randomly deposited molecule-interconnected metal nanoparticles, which act collectively as strongly nonlinear single-electron transistors. Disorder is being incorporated in the modeling of their electrical behavior and the collective response of interacting nano-components is being rationalized. The non-optimized energy consumption of the synaptic grid for a "then-if" logical computation is in the range of few aJ.
