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...
Formation of ordered nanoscale semiconductor dots by ion sputtering (1999)
Facsko, Stefan, Dekorsy, Thomas, Koerdt, Clemens, Trappe, Cyril, Kurz, Heinrich, Vogt, Alexander, ...
A formation process for semiconductor quantum dots based on a surface instability induced by ion sputtering under normal incidence is presented. Crystalline dots 35 nanometers in diameter and...
