Figure 1From: Evaluation of optical and electronic properties of silicon nano-agglomerates embedded in SRO: applying density functional theoryBackscattering Raman spectra. (a) Ro = 10 sample, in the region from 350 to 700 cm−1 after different annealing times. (b) Ro = 10, 20, and 30 after 30 min of annealing. The inset is a zoom of the Raman spectra for Ro = 20.Back to article page
