用不同的激发激光功率和波长测量了不同尺寸Ge纳米线的拉曼光谱。通过消除样品在光照下的加热，小尺寸纳米线的声子限制效应被清楚地识别。
Raman spectra for different size Ge nanowires were measured with different excitation laser powers and wavelengths. By eliminating the heating of the sample under illumination, the phonon confinement effect for small size nanowires was clearly identified.
