dc.description | We report low-temperature (77 K) photoreflectance measurements in two Ge/Ge0.7Si0.3 strained-layer superlattices, in the photon energy range 0.8-1.8 eV. The multiple lines observed in our spectra in this energy region can be consistently explained in terms of quantum confinement of zone-center bulk Ge states. Quantitative agreement is obtained when energy-dependent masses are used for the electrons and light-hole states within a scalar three-band model. This interpretation leads to values of the average valence-band offsets in good agreement with previous ab initio theoretical calculations. | |
