TL;DR: Comparison of multilayered sheets revealed that the conductivity of the undermost layer is reduced by a factor of more than 2 as a consequence of the interaction with the Si/SiO2 substrate.

TL;DR: In this paper, the authors demonstrate photocurrent imaging as a fast and effective tool to locate charge transport barriers within individual metallic nanotubes contacted by metal electrodes, which directly reflect the existence of built-in electric fields associated with the presence of depletion layers at the contacts or structural defects along the tubes.

TL;DR: In this article, the effect of surface-enhanced Raman scattering on individual single-walled carbon nanotubes covered with isolated gold particles was investigated using confocal optical microscopy.

TL;DR: In this article, single-wall carbon nanotubes decorated by gold nanoparticles with sizes of a few tens of nanometers were investigated by confocal Raman microscopy, and it was found that individual nanoparticles impart a sizable Raman enhancement exceeding one order of magnitude, without appreciably interfering with polarization dependent Raman measurements.

TL;DR: A one-dimensional heterostructure comprising single-walled carbon nanotubes (CNTs) and CdSe nanowires is prepared via electrochemical deposition of Bi nanoparticles onto the nanot tubes, followed by solution–liquid–solid synthesis of the semiconductor nanowire.
