Abstract

GaAs-AlGaAs core-shell nanowires were grown on anodized-aluminum- oxide (AAO) patterned-Si (111) via molecular beam epitaxy. Reciprocal space maps and phonon modes of the nanowires exhibited lattice parameter deformation and strain relaxation. Results show the relation of the strain experienced by the nanowires with the nanowire diameter.
