Figure 3From: The role of the surfaces in the photon absorption in Ge nanoclusters embedded in silica Transmittance and reflectance spectra. Transmittance spectra for the bare substrate (quartz, continuous line) and for the as-deposited and annealed SiGeO samples (symbols). The reflectance spectrum (R) for the SiGeO sample after annealing at 800°C is also reported (dotted line) (color online).Back to article page
