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…
Near-forward Raman selection rules of the phonon-polariton created by alloying in (Zn,Be)Se
H. Dicko, O. Pages, F. Firszt +5
The Raman selection rules of the (ZnSe, BeSe) mixed phonon polariton created by alloying in the three mode (1ZnSe, 2BeSe) ZnBeSe system, whose dramatic S like dispersion covers the…
Pressure-induced phonon freezing in the ZnSeS II-VI mixed crystal: phonon-polaritons and ab initio calculations
R. Hajj Hussein, O. Pages, A. Polian +8
Near-forward Raman scattering combined with ab initio phonon and bond length calculations is used to study the phonon-polariton transverse optical modes (with mixed electrical and…
Near-forward Raman study of a phonon-polariton reinforcement regime in the Zn(Se,S) alloy
Rami Hajj Hussein, Olivier Pagès, Franciszek Firszt +4
We investigate by near-forward Raman scattering a presumed reinforcement of the (A-C,B-C)-mixed phonon-polariton of a A1-xBxC zincblende alloy when entering its longitudinal optica…
Near-forward Raman scattering by bulk and surface phonon-polaritons in the model percolation-type ZnBeSe alloy
Rami Hajj Hussein, Olivier Pagès, Franciszek Firszt +2
We study the bulk and surface phonon-polaritons of the Zn0.67Be0.33Se zincblende alloy by near-forward Raman scattering. The short (Be-Se) bond exhibits a distinct percolation doub…
Pressure-induced phonon-freezing in the ZnBeSe alloy: a study via the percolation mesoscope
Gopal K. Pradhan, Chandrabhas Narayana, Olivier Pages +8
We use the 1-bond -> 2-phonon percolation doublet of zincblende alloys as a mesoscope for an unusual insight into their phonon behavior under pressure. We focus on (Zn,Be)Se and sh…
