Silicon nanocrystals (nc-Si) embedded in SiO 2 glassy mixture have been prepared on glass substrates and silicon and germanium wafers by r.f. co-sputtering and post-annealing in a vacuum. Using Raman spectrometry, photoluminescence and electrical conductivity measurements, we have investigated the s
Si nanocrystals (Si-ncs) embedded in SiO 2 /SiN x multilayer structures can be of interest for optoelectronic devices such as solar cells. However, controlling the size and density of the Si-ncs is strongly requested for an efficient use in a functioning solar cell device. In this work, SiO 2 and S
