Due to their specific properties, silicon nanocrystals (Si-nc) embedded in dielectric matrix have recently attracted much interest for their use in silicon-based...

In order to understand the mechanisms of the heat transport in very thin amorphous films, we have proposed and experimentally demonstrated a new technique to measure...
