Abstract
Abstractmagnified imageThe radial alloy distribution of Inx Ga1–xN nanowires grown by plasma‐assisted molecular beam epitaxy has been investigated by three different techniques with nanometric spatial resolution and capability to study single nanowires. Energy‐dispersive X‐ray spectroscopy radial line‐scans revealed a gradient in the alloy composition of individual nanowires. Resonant Raman scattering and spatially resolved X‐ray diffraction showed the existence of three distinctive regions with different alloy composition. The combination of the three techniques provides robust evidence of the spontaneous formation of a core–shell structure with a thin Ga‐richer shell wrapping an In‐rich core at the bottom part of the nanowires. This composition‐modulated nanostructure offers an attractive way to explore new device concepts in fully epitaxial nanowire‐based solar cells. (© 2013 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
