TL;DR: In this article, a metal-island cell structure that makes quasi-abatic switching possible for quantum-dot cellular automata (QCA) has been presented for gated semiconductor cells.

TL;DR: In this Perspective, Lent discusses the advantages of an alternative route to molecular electronics, quantum-dot cellular automata, which store binary information in a charge configuration instead of a current switch.

TL;DR: Characterization of the array of surface bound complexes with spectroscopic as well as electrochemical techniques confirms the presence of strongly bound, chemically robust, mixed-valence complexes and passage through the capacitance maximum corresponds to switching of the molecular quantum cellular automata (QCA) cell array by the electric field.

TL;DR: A promising alternative to clocking requires only altering the timing of the clocking signals so that bit information is simply held in place by the clock until a computational block is complete, then erased in the reverse order of computation, which results in ultralow power dissipation without additional circuit complexity.

TL;DR: Scanning tunnelling microscopy is used to study self-assembled monolayers of ferrocenecarboxylic acid (FcCOOH), and it is found that, rather than producing dimeric or linear structures typical of car boxylic acids, FcCOSH forms highly unusual cyclic hydrogen-bonded pentamers, which combine to form two-dimensional quasicrystallites that exhibit local five-fold symmetry and maintain translational
