Phase change in Ge2Sb2Te5 films investigated by coherent phononspectroscopy (2000)
Först, Michael, Dekorsy, Thomas, Trappe, Cyril, Laurenzis, Martin, Kurz, Heinrich, Béchevet, B.
Amorphous and crystalline phases of Ge2Sb2Te5 films are investigated by coherent phonon spectroscopy. By heating amorphous films above specific temperatures, the coherent phonon signatures exhibit...
