Germanium nanowires sheathed with an oxide layer

First-principles study of the structural, electronic, and optical properties of oxide-sheathed silicon nanowires.

Using a density functional theory approach, we examine the dielectric function (ε(ω)) optical spectra and electronic structure of various silicon nanowire (SiNW) orientations (<100>, <110>, <111>, and <112>) with amorphous oxide sheaths (-a-SiOx) and compare the results against H-terminated reference SiNWs. We extend the same methods to investigate the effects of surface passivation on <111> Si...

BN tubular layer-sheathed CaS:Eu(2+) nanowires as stable red-light-emitting nanophosphors.

Novel chemically stable CaS:Eu(2+) nanowires protected by BN tubular sheaths were synthesized via a one-step and catalyst-free method for the first time; the nanostructures showed a red-light emission when excited by approximately 450 nm blue light.

Synthesis and Characterization of Nanowires Zinc Oxide with Different Temperatures

Reliability enhancement of germanium nanowires using graphene as a protective layer: aspect of thermal stability.

We synthesized thermally stable graphene-covered Ge (Ge@G) nanowires and applied them in field emission devices. Vertically aligned Ge@G nanowires were prepared by sequential growth of the Ge nanowires and graphene shells in a single chamber. As a result of the thermal treatment experiments, Ge@G nanowires were much more stable than pure Ge nanowires, maintaining their shape at high temperature...

Gold Catalyzed Germanium Nanowires on Titanium

Germanium nanowires have been grown successfully on titanium. The wires are single crystal, with some low angle stacking faults and other defects. Growth of nanowires on metal substrates offers reduced cost over single crystal substrates, while still offering an electrical contact to the wire core for core-shell junction structures. Summary of Research: Figure 1: 80 nm germanium nanowires on a ...
