摘要

The Raman scattering of a self-organized Ge dot superlattice is reported. Phonon confinement effect is observed for the embedded Ge dots in Si matrix. Due to the inter-sub-level transition between the first two confined heavy vole (HH) states in the Ge quantum dots, an optical transition at 1890 cm-1 has been observed in the polarized Raman spectrum. A method for developing improved Si-based mid-infrared detectors is provided.
