Cubic-Zn(1-x)Mn(x)Te optical modes across the phonon and phonon-polariton regimes
M. Mina, A. Elmahjoubi, T. Ngulezhu +18
Alloying offers a convenient route to tune the physical properties of semiconductors, at the price, however, of local lattice/bond distortions needed to accommodate the lattice mis…
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…
Vibrational and mechanical properties of the highly mismatched (Cd,Be)Te semiconductor alloy : Experiment and ab initio calculations
A. Elmahjoubi, M. B. Shoker, O. Pages +18
The (Cd, Be)Te semiconductor alloy that exhibits a dramatic mismatch in bond covalency and stiffness clarifying its vibrational and mechanical properties is used as a benchmark to…
