    Measurements of thermal transport along 3C-SiC nanowires with and without a gold coating on the end(s) suggest that thermally excited surface phonon polaritons can be used in nanostructures to substantially enhance thermal conductivity.

    Valentini et al. devise a method through which they can perform both tunnelling spectroscopy and Coulomb blockade spectroscopy on the same hybrid nanowire island to reduce ambiguities in the detection of Majorana.

    Spin correlation experiments are demonstrated in an electron entangler device based on the ‘splitting’ of Cooper pairs from a superconductor, which can potentially be used to investigate many fundamental phases and processes related to the electron spin.

    A hexagonal (rather than cubic) alloy of silicon and germanium that has a direct (rather than indirect) bandgap emits light efficiently across a range of wavelengths, enabling electronic and optoelectronic functionalities to be combined on a single chip.

    Crystal phase switching between zinc-blende and wurtzite phases during the growth of gallium arsenide nanowires is observed experimentally, and explained via changes in the geometry of the catalytic droplet sitting on top of the growing nanowire.

    The splitting of zero-energy Majorana modes in a tunnel-coupled InAs nanowire with epitaxial aluminium is exponentially suppressed as the wire length is increased, resulting in protection of these modes; this result helps to establish the robust presence of Majorana modes and quantifies exponential protection in nanowire devices.

    The ‘0.7-anomaly’ — an unexpected feature in the conductance of a quantum point contact — is shown to originate in a smeared van Hove singularity in the local density of states at the bottom of the lowest one-dimensional subband of the point contact.

    Aluminium catalyst is trapped during growth of a silicon nanowire from vapour phase at concentrations vastly beyond equilibrium solid solubility, but is homogeneously distributed as atoms and not found as clusters or precipitates; this is a potential route to tailoring the composition and properties of nanowires.

    Net laser cooling from 290 kelvin to about 250 kelvin is achieved in semiconductor cadmium sulphide ‘nanobelts’ and attributed to strong coupling between excitons and longitudinal optical phonons.

    Aerotaxy, an aerosol-based growth method, is used to produce gallium arsenide nanowires with a growth rate of about 1 micrometre per second, which is 20 to 1,000 times higher than previously reported for traditional nanowires and allows sensitive and reproducible control of the nanowires’ optical and electronic properties.

    A long-standing issue in nanotechnology is how to connect molecular electronic devices. A method for splicing nanoscale wires made from different materials paves the way for a solution to this problem.

    In a significant step forward in complexity and capability for bottom-up assembly of nanoelectronic circuits, this study demonstrates scalable and programmable logic tiles based on semiconductor nanowire transistor arrays. The same logic tile, consisting 496 configurable transistor nodes in an area of about 960 μm2, could be programmed and operated as, among other functions, a full-adder, full-subtractor and multiplexer. The promise is that these logic tiles can be cascaded to realize fully integrated nanoprocessors with computing, memory and addressing capabilities.

    Nanowires are candidates for enabling the exchange of quantum information between light and matter. The rapid control of a single electron spin by solely electrical means brings this possibility closer. See Letter p.1084

    Motion of electrons can influence their spins through a fundamental effect called the spin–orbit interaction. Here, a spin–orbit quantum bit (qubit) is implemented in an indium arsenide nanowire, which should offer significant advantages for quantum computing. The spin–orbit qubit is electrically controllable, and information can be stored in the spin. Moreover, nanowires can serve as one dimensional templates for scalable qubit registers, and are suited for both electronic and optical devices.

    There is much interest in graphene for applications in ultrahigh-speed radio-frequency electronics, but conventional device fabrication processes lead to significant defects in graphene. Here a new way of fabricating high-speed graphene transistors is described. A nanowire with a metallic core and insulating shell is placed as the gate electrode on top of graphene, and source and drain electrodes are deposited through a self-alignment process, causing no appreciable damage to the graphene lattice.
