Abstract

Field-coupled nanocomputing (FCN) paradigms offer fundamentally new approaches for digital computing. As one of several FCN paradigms currently under active investigation, Molecular Quantum-dot Cellular Automata (MQCA) is based upon electrostatic interactions among quantum dot cells that does not require charge transport. Hence its energy dissipation is significantly reduced. Moreover, an external clock signal has to be adopted desirably while controlling switch in QCA devices. In this paper, with the aim of analyzing information propagation on clocked molecular QCA device from an electronic point of view, an effective algorithm has been implemented relied on data obtained from ab-initio simulations, electrostatic equations and models of the molecular interaction. The quantitative results generated from the algorithm depict correct behaviors of clocked QCA devices and provide important feedback for future QCA experimental implementation.
