High frequency phonon transmission through amorphous films [article]

Joachim Mebert, Bernd Maile, Wolfgang Eisenmenger, Universität Stuttgart, Universität Stuttgart
We now report on phonon spectroscopy measurements in the frequency range from 300 GHz - 1 THz on thin amorphous films of several materials (i.e. e-beam evaporated SiO2., α-Si and α-Ge). Some films were prepared in a residual gas atmosphere as H20 and N2.
