Raman spectra of \(S i / G e_{x} S i_{1-x}\) superlattices have been measured, probing close to the mini Brillouin zone edge. The data reveal sharp lines appearing between those of folded phonon doublets. These lines have been interpreted with the aid of a computational method based on the photoelas
