Abstract
Raman spectroscopy is used to study the optical phonon properties of Si/Ge strained layer superlattices grown on (110) Ge buffers. Built in biaxial strain leads to an energetic shift and splitting of the two TO phonon branches. Narrow layered structures give rise to the formation of optical confined modes which are observed up to the third order.
