Effect of silicon nitride/oxide on the structure and the thermal conductivity of CoSi nanocomposites

Ioannou, M.; Delimitis, A.; Symeou, E.; Giapintzakis, John; Kyratsi, Theodora (2017)

In this work, the fabrication of nanocomposites with silicon nitride/oxide into the thermoelectric matrix of cobalt silicide is presented. The different concentrations of nano-Si3N4 were intentionally introduced by mechanical ...

Thermal oxidation and facet-formation mechanisms of Si nanowires

Kioseoglou, J.; Komninou, P.; Zervos, Matthew (2014)

Silicon nanowires were grown along the [111] direction on Si(001) by the vapor-liquid-solid mechanism using 1 nm Au as a catalyst. They were subsequently oxidized at 900 °C for 60 min, 120 min and 180 min, which lead to ...

Ultrafast time-resolved spectroscopy of Si nanocrystals embedded in SiO2 matrix

Lioudakis, Emmanouil E.; Emporas, A.; Othonos, Andreas S.; Nassiopoulou, Androula Galiouna (2009)

In this work, we present a comprehensive study of ultrafast transient photoinduced absorption of silicon nanocrystals (NCs) embedded in SiO2 matrix. The samples under investigation are single monolayers of Si-NCs embedded ...
