Abstract
By experimentally examining and theoretically analyzing the Raman spectra of SixGe1−x nanocrystal-embedded silica films, we show that the 430 cm−1 Si–Si optical phonon mode can be used as a fingerprint to identify the existence of local silicon cluster nanostructures inside SixGe1−x nanocrystals with high silicon content.Keywords
