“…The thermal conductivity (k) of neat PEEK resin is $0.23 W m À1 K À1 [28], and that of glass fiber fabric around 0.05 W m À1 K À1 [36]. Phonon transport in these composites is in the form of diffusion, and since CNTs exhibit ballistic transport properties [37], the dispersion of CNTs into the matrix will significantly enhance phonon diffusion, thereby improving thermal conductivity. The room temperature outof-plane thermal conductivity values of the different manufactured composites are shown in Fig.…”

“…Nanotubes provide unique systems suitable for electronics, showing one-dimensional ballistic electron transport [47,48,49] and remarkably long spin coherence lengths [50]. Nanotubes can be side-gated with selfaligned, regularly spaced metal electrodes tens of nanometers wide [51].…”

Abstract. Molecular structures appear to be natural candidates for a quantum technology: individual atoms can support quantum superpositions for long periods, and such atoms can in principle be embedded in a permanent molecular scaffolding to form an array. This would be true nanotechnology, with dimensions of order of a nanometre. However, the challenges of realising such a vision are immense. One must identify a suitable elementary unit and demonstrate its merits for qubit storage and manipulation, including input / output. These units must then be formed into large arrays corresponding to an functional quantum architecture, including a mechanism for gate operations. Here we report our efforts, both experimental and theoretical, to create such a technology based on endohedral fullerenes or 'buckyballs'. We describe our successes with respect to these criteria, along with the obstacles we are currently facing and the questions that remain to be addressed.

We calculate the resistance and mean free path in long metallic and semiconducting silicon nanowires (SiNWs) using two different numerical approaches: A real space Kubo method and a recursive Green's function method. We compare the two approaches and find that they are complementary: depending on the situation a preferable method can be identified. Several numerical results are presented to illustrate the relative merits of the two methods. Our calculations of relaxed atomic structures and their conductance properties are based on density functional theory without introducing adjustable parameters. Two specific models of disorder are considered: Un-passivated, surface reconstructed SiNWs are perturbed by random on-site (Anderson) disorder whereas defects in hydrogen passivated wires are introduced by randomly removed H atoms. The un-passivated wires are very sensitive to disorder in the surface whereas bulk disorder has almost no influence. For the passivated wires, the scattering by the hydrogen vacancies is strongly energy dependent and for relatively long SiNWs (L > 200 nm) the resistance changes from the Ohmic to the localization regime within a 0.1 eV shift of the Fermi energy. This high sensitivity might be used for sensor applications.
