Abstract
Pure zinc blende structure GaAs/AlGaAs axial heterostructure nanowires (NWs)
are grown by metal organic chemical vapor deposition on GaAs(111) B substrates using
Au-catalyzed vapor-liquid-solid mechanism. Al adatom enhances the influence of
diameters on NWs growth rate. NWs are grown mainly through the contributions from
the direct impingement of the precursors onto the alloy droplets and not so much
from adatom diffusion. The results indicate that the droplet acts as a catalyst
rather than an adatom collector.
