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…
Comment on Infrared dielectric function of Ga(As,P) semiconductor alloys near the reststrahlen bands (Applied Physics Letters 123, 172102, 2023)
A. Elmahjoubi, T. Alhaddad, A. V. Postnikov +1
Though extensively studied since the emergence of zincblende cubic A(B,C) semiconductor alloys (zb-SCA) in the sixties, the phonon mode behavior of Ga(As,P) remains a subject of de…
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…
