Abstract

original image

A new simple vapor-phase route to germanium nanowires (see Figure) has been developed that relies on a combination of germanium plus carbon in the original reactant source. A layer of erbium ions grown along the surface of these nanowires produces a core–shell structure that emits in the near-infrared range.
