Observation of T(2)-like coherent optical phonons in epitaxial Ge(2)Sb(2)Te(5)/GaSb(001) films

The phonon spectrum of Ge(2)Sb(2)Te(5) is a signature of its crystallographic structure and underlies the phase transition process used in memory applications. Epitaxial materials allow coherent optical phonons to be studied in femtosecond anisotropic reflectance measurements. A dominant phonon mode...
