摘要：

We have studied the piezoreflectance (PzR) and photoreflectance (PR) spectra at 77 K of a series of short-period Si/Ge superlattices grown on Ge(001) substrates. These samples are similar to those measured using electroreflectance (40 K) by Pearsall et al. [Phys. Rev. Lett. 63 (1989) 2104]. We have observed several low-energy features in the PzR data just above the direct band gap of Ge. They are clearly due to quantum-confined direct transitions in the Ge spacer region, not pseudodirect transitions in the short-period Si/Ge portion of the samples as reported by Pearsall et al.
