    "abstract": "The observation of pure phonon confinement effect in germanium nanowires is\nlimited due to the illumination sensitivity of Raman spectra. In this paper we\nmeasured Raman spectra for different size germanium nanowires with different\nexcitation laser powers and wavelengths. By eliminating the local heating\neffect, the phonon confinement effect for small size nanowires was clearly\nidentified. We have also fitted the Raman feature changes to estimate the size\ndistribution of nanowires for the first time.",
