Abstract
The notion of quantum-dot cellular automata (QCA) as a possible replacement paradigm for conventional transistor-based logic is reviewed. Experiments using metal tunnel structures demonstrating a functional QCA cell are prese nted. It is shown that single electron tunnelling transistors used as elect rometers verify proper switching of the QCA cell. Additionally, we provide evidence for a QCA cell switching frequency of 14 MHz, and a calculated upp er limit of more than 5 GHz.
