Nanoparticle based boolean logic

Arrays of passivated gold nanoparticles have been shown to exhibit single electron transport behavior at room temperature. The ratio of the self-capacitance to the interparticle capacitance is very different to that reported for single electron devices fabricated using traditional methods. This ratio suggests that novel device behavior may be possible in organized arrays of nanoparticles. We report on simulations of single electron logic circuits designed using parameters expected for circuits made using passivated gold nanoparticles. We will show AND- and NAND-gate behavior from an electron-pump gated one-dimensional array of nanoparticles. (C) 2003 Elsevier B.V. All rights reserved.
