Strain and phonon shifts in GaAs12xPx alloys
نویسندگان
چکیده
We have studied the influence of an in-plane ~001! strain on the energy position of the long wavelength optical modes of GaAs12xPx alloys. These alloys have a two mode behavior. We have observed that the strain-induced shift of the Raman peaks corresponding to the GaAs-like vibration is greater than that of the GaP-like vibration. This result shows that the two modes are not affected in the same way by the strain. © 1996 American Institute of Physics. @S0003-6951~96!00613-3#

Optical properties of InxGa1-xN alloy and In0.5Ga0.5N/GaN multi quantum wells have been investigated in the region of far infrared. Far-IR reflectivity spectra of In0.5Ga0.5N/GaN multi quantum wells on GaAs substrate have been obtained by oblique incidence p- and s-polarization light using effective medium approximation. The spectra and the dielectric functions response give a good informa...
متن کاملRaman-scattering study of GaP/InP strained-layer superlattices.
Strained-layer superlattices (SL's) made up of alternate GaP and InP layers constitute a system where the strain is symmetrized when grown on GaAs substrates. While both components present a large lattice mismatch to GaAs ( —3.6% GaP, +3.8% InP) giving rise to large biaxial deformations in the individual layers, the net value of strain in the whole SL is very small, thus favoring their stabilit...
متن کاملFirst-principles calculation of phase equilibrium of V-Nb, V-Ta, and Nb-Ta alloys
In this paper, we report the calculated phase diagrams of V-Nb, V-Ta, and Nb-Ta alloys computed by combining the total energies of 40–50 configurations for each system (obtained using density functional theory) with the cluster expansion and Monte Carlo techniques. For V-Nb alloys, the phase diagram computed with conventional cluster expansion shows a miscibility gap with consolute temperature ...
متن کاملVisible and ultraviolet Raman scattering studies of Si1ÀxGex alloys
We report Raman studies of the Si–Si phonon band in Si12xGex alloys, where the excitation is by visible and ultraviolet ~351 nm! light. At a wavelength 351 nm, the optical penetration depth is extremely shallow ~'5 nm!. By varying the excitation from 351 to 514 nm, the optical penetration depth spans from 5 to 300 nm. Two sets of samples were examined. Thin layers grown using molecular beam epi...
متن کاملComposition dependence of the phonon strain shift coefficients of SiGe alloys revisited
By combining Raman scattering from the cleaved edge and under hydrostatic pressure, we have accurately determined the tetragonal phonon deformation potentials of strained Si1−xGex alloys in the entire compositional range for the Ge-like, Si-like, and mixed Si–Ge optical modes. A known biaxial strain is induced on thin alloy layers by pseudomorphic epitaxial growth on silicon and subsequent capp...
