    As manufacturing technology reaches nanoscale, architectural designs need to accommodate the uncertainty inherent at such scales. These uncertainties are germane in the minuscule dimension of the devices, quantum physical effects, reduced noise margins, system energy levels reaching computing thermal limits, manufacturing defects, aging, and many other factors. Defect-tolerant architectures and th... View full abstract»

    In the emerging nanotechnologies, faulty components may be an integral part of a system. For the system to be reliable, the error of the building blocks has to be smaller than a threshold. Therefore, finding exact error thresholds for noisy gates is one of the most challenging problems in fault-tolerant computations. Under the von Neumann's probabilistic computing framework, we show that computati... View full abstract»

    Recent experiments have been able to measure the conductance of individual molecules by repeatedly raising and lowering a gold-plated atomic force microscope tip into a self-assembled monolayer on a gold substrate, as demonstrated by Xu and Tao and Xiao et al. Upon raising the tip after it has formed several metal-molecule-metal junctions and recording the current simultaneously, the experiments r... View full abstract»

    Individual gold nanoparticles exhibit discrete capacitances of the order of 1 aF, and they can be tethered to a conductive substrate using a bi-functional monolayer of a suitable organic molecule. However the conduction, retention and leakage of charge by such an attached "nanocapacitor" will be an important issue in any practical application of this concept. Here we investigate the electrical pro... View full abstract»

    We present an approach, and its implementation in a computer program, for the three-dimensional (3-D) simulation of realistic single electron transistor (SET) structures, in which subregions with different degrees of quantum confinement are simultaneously considered. The proposed approach is based on the self-consistent solution of the many body Schrodinger equation with density functional theory ... View full abstract»

    The effects of terminal groups on the electron transport between metal electrodes and molecule are investigated through metal-molecule-metal systems using the first principles method, which is based on the density functional theory, with norm-conserving nonlocal pseudopotentials and nonequilibrium Green's functions. Eight Au-molecule-Au open systems are constructed and numerically examined, where ... View full abstract»

    Inorganic transition metal complexes were identified as potential candidates for transistor-like behavior in an electrochemical scanning tunnelling microscope (STM) configuration at room temperature. The theoretical background has been established based on condensed matter charge transfer theory. It predicts a distinct increase of the tunnelling current close to the equilibrium potential, i.e., if... View full abstract»

    This paper presents a novel method for the implementation of wire-crossing networks using quantum-dot cellular automata (QCA) cells. Such wire-crossing networks, also called crossbar networks, are an important part of modern programmable logic devices, such as programmable arrays of logic. The crossbar networks are made possible through the use of parallel-to-serial converters and special regions ... View full abstract»

    Motivated by the need for economical fault-tolerant designs for nanoarchitectures, we explore a novel multiplexing-based redundant design scheme at small (≤100) and very small (≤10) redundancy factors. In particular, we adapt a strategy known as von Neumann multiplexing to circuits of majority gates with three inputs and for the first time exactly analyze the performance of a multiplexing sc...

    In this paper, a curvilinear coordinate system is used in space and in k-space to study the energy band of single-walled carbon nanotubes wrapped at a helical angle. Using this method, a general function of the bandgap associated with the radius of the tube and the helical angle is derived based on the tight-binding theory. The three-dimensional hexagonal Brillouin zone of the tube is on the surfa... View full abstract»

    We present our magnetooptical Kerr effect (MOKE) studies on picosecond spin dynamics in closely spaced rectangular Co dots with sizes ranging from 2×6 μm2 down to 100 × 300 nm2 under in-plane, picosecond, magnetic pulse excitation. A low-temperature-grown GaAs photoconductive switch, excited by femtosecond laser pulses, was used to produce ∼25-ps-long magne... View full abstract»

    We propose a novel parameter-free effective potential scheme for use in conjunction with particle-based simulations. The method is based on a perturbation theory around thermodynamic equilibrium and leads to an effective potential scheme in which the size of the electron depends upon its energy. The approach has been tested on the example of a MOS-capacitor by retrieving the correct sheet electron... View full abstract»

    Resonant tunneling-based random-access memories (TRAMs) have recently garnered a great amount of interest among memory designers due to their intrinsic merits such as reduced power consumption by elimination of refreshing operation, faster read and write cycles, and improved reliability in comparison to conventional silicon dynamic random access memories (DRAMs). In order to understand the precise... View full abstract»
