Abstract
The vibrational spectrum of short-period GaSb/A1Sb superlattices in th e frequency range of GaSb optical phonons is investigated in detail. L ocalization of transverse GaSb optical phonons in GaSb/A1Sb superlatti ces is observed experimentally for the first time. The dispersions of TO and LO phonons in GaSb are measured.
