Description

We study the excitation wavelength dependence of the Raman spectra of InN nanowires. The E1(LO) phonon mode, which is detected in backscattering configuration because of light entering through lateral faces, exhibits an upward frequency shift that can be explained by Martin's double resonance. The E1 (LO)/E2h intensity ratio increases with the excitation wavelength more rapidly than the A1(LO)/E2h ratio measured in InN thin films. (copyright 2012 WILEY-VCH Verlag GmbH and Co.
