Abstract:

Zinc-blende-type InSb nanowire arrays with different growth orientations were synthesized in porous anodic alumina membrane by pulse electrodeposition. It is found that the growth orientation of InSb nanowires changes from [400] to [220] direction by controlling the concentration of sodium dodecyl sulfate(SDS) in the electrolyte. The phases and microstructure of the obtained nanowires were analyzed using powder X-ray diffraction, scanning electron microscopy and high-resolution transmission electron microscopy. The laser Raman spectra of the InSb nanowire arrays grown along different directions show distinctly different Raman features. Compared with the bulk materials, the phonon scattering peaks of the InSb nanowire arrays are severely red-shifted while its corresponding absorption band is blue-shifted.

Key words: InSb, Nanowire, Raman spectrum, Infrared absorbance spectrum
