Figure 1

Structural characterization of GaAs NWs. (a) SEM image of highly Zn-doped GaAs NWs on GaAs substrate recorded at a tilt angle of 30°. The typical length of the NWs is ~3 µm with a few NWs longer than 8 µm. (b) TEM image of a section of a GaAs NW with a 5 nm Al2O3 coating and with a nominally 10 nm Au layer around it. The Au film is not continuous, and Au islands and nanoparticles are formed instead.
