Abstract

This paper presents the results of PL spectrum studies for Si nano-clusters in an amorphous silicon matrix. The four amorphous Si layers were prepared by the hot-wire CVD method on glass substrates at a temperature of 250 ∘C and different filament temperatures in the range of 1650–1950 ∘C. The joint analysis of PL and X ray diffraction results dependant on technological conditions has been done. PL bands deal with Si nanocrystals and amorphous Si nanoclusters are discussed as well.
