Study on phase separation in a-SiO x for Si nanocrystal formation through the correlation of photoluminescence with structural and optical properties

► We study the phase separation in a-SiO x for the formation of Si nanocrystals. ► The phase separation includes two separate processes that should be distinguished. ► The precipitated Si atoms exist first as amorphous Si clusters and then crystallize. ► The structural and optical properties and the...
