Phonon-polaritons in Zn(1-x)MgxTe (x<0.09): A Raman scattering study

D. Singh, A. Elmahjoubi, O. Pages +10

Phonon-polaritons (PP) are phonon-photon coupled modes. Using near-forward Raman scattering, the PP of the cubic Zn(1-x)MgxTe (x<0.09) semiconductor alloy could be measured. While…

Lattice dynamics of hexagonal ZnMgS

Abdelmahjid Elmahjoubi, Mala Rao, Alexandre Ivanov +10

Inelastic neutron scattering measurements on the hexagonal Zn67Mg33S semiconductor alloy reveal a bimodal pattern of the optical modes across the Brillouin zone, confirmed by first…

Multiscale insight into the Cd1-xZnxTe vibrational-mechanical properties -- High-pressure experiments and ab initio calculations

Toni Alhaddad, Mohamad Shoker, Olivier Pages +10

The Cd1-xZnxTe semiconductor alloy is a regular system regarding its macroscopic mechanic properties in that its experimental bulk modulus exhibits a linear x-dependence, in line w…

Phonon-based partition of (ZnSe-like) semiconductor mixed crystals on approach to their pressure-induced structural transition

M. B. Shoker, O. Pagès, V. J. B. Torres +10

The generic 1-bond:2-mode percolation type Raman signal inherent to the short bond of common (A,B)C semiconductor mixed crystals with zincblende (cubic) structure is exploited as a…

Lipschitz Simplicial Volume of Connected Sums

Karol Strzałkowski

We prove that the locally finite simplicial volume and the Lipschitz simplicial volume are additive with respect to certain gluings of manifolds. In particular, we prove that in di…
