Pressure dependence of the Boson peak in glassy As2S3 studied by Raman Scattering
K. S. Andrikopoulos, D. Christofilos, G. A. Kourouklis +1
A detailed pressure-dependence study of the low-energy excitations of glassy As2S3 is reported over a wide pressure range, up to 10 GPa. The spectral features of Boson peak are ana…
Raman scattering study of the a-GeTe structure and possible mechanism for the amorphous-to-crystal transition
K. S. Andrikopoulos, S. N. Yannopoulos, G. A. Voyiatzis +3
We report on an inelastic (Raman) light scattering study of the local structure of amorphous GeTe films. A detailed analysis of the temperature-reduced Raman spectra has shown that…
On the analysis of the vibrational Boson peak and low-energy excitations in glasses
S. N. Yannopoulos, K. S. Andrikopoulos, G. Ruocco
Implications of reduction procedures applied to the low energy part of the vibrational density of states in glasses and supercooled liquids are considered by advancing a detailed c…
Pressure screening in the interior of primary shells in double-wall carbon nanotubes
J. Arvanitidis, D. Christofilos, K. Papagelis +6
The pressure response of double-wall carbon nanotubes has been investigated by means of Raman spectroscopy up to 10 GPa. The intensity of the radial breathing modes of the outer tu…
