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…
Regularity in the intratube interaction in double-wall carbon nanotubes
J. Arvanitidis, D. Christofilos, K. Papagelis +5
High pressure Raman experiments were performed on bundled double wall carbon nanotubes (DWCNTs). We observe peculiar regularity in the strength of the inner-outer tube (intratube)…
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…
Raman spectra of MgB2 at high pressure and topological electronic transition
K. P. Meletov, J. Arvanitidis, M. P. Kulakov +2
Raman spectra of the MgB2 ceramic samples were measured as a function of pressure up to 32 GPa at room temperature. The spectrum at normal conditions contains a very broad peak at…
