Abstract: A complete Raman study of GaP nanowires is presented. By comparison with the Raman spectra of GaP bulk material, microcrystals and nanoparticles, we give evidence that the Raman spectrum is affected by the one-dimensional shape of the nanowires. The Raman spectrum is sensitive to the polarization of the laser light. A specific shape of the overtones located between 600 and 800 cm -1 is actually a signature of the nanowires. Some phonon confinement and thermal behavior is also observed for nanowires. Copyright EDP Sciences/Società Italiana di Fisica/Springer-Verlag 2005
