TL;DR: The realization and characterization of low n-type Schottky barriers formed at epitaxial contacts between Au-In alloy catalytic particles and GaAs-nanowires are reported, and the insight into the physical mechanisms behind the observed low-energy SchOTTky barrier may guide future efforts to engineer abrupt nanoscale electrical contacts with tailored electrical properties.

TL;DR: In this article, the authors report intrinsically deactivation resistant nanoplasmonic hydrogen sensors enabled by a rationally designed ternary PdAuCu alloy nanomaterial, which combines the identified best intrinsic attributes of the constituent binary Pd alloys.

TL;DR: Radio frequency single-electron transistors fabricated from epitaxially grown InAs/InP heterostructure nanowires show typical 1/f noise behavior, with a level extrapolated to 300 microe rms Hz(-1/2) at 10 Hz.

TL;DR: In this paper, different in-situ characterization techniques, in particular transmission electron microscopy (TEM), X-ray diffraction (XRD), and Xray absorption spectroscopy (XAS), were applied to follow the reduction and alloying process of Cu-Ni nanoparticles on silica.

TL;DR: Two novel types of TEM specimen holder that enable in situ illumination are developed to study light-induced phenomena in photoactive materials, systems and photocatalysts at the nanoscale under working conditions.
