Phonon shifts and strains in strain
We have measured the phonon frequencies (Raman technique) and the strains (x-ray rocking curve technique) of (Gal _ x lnx ) As films on GaAs (i 00) substrates. Films with various x values and various thicknesses were studied. The films range from perfect epitaxial to those that have relaxed by different amounts. The strain-induced frequency shift was calculated for each sample using the phonon ...
متن کاملPolaronic signatures and spectral properties of graphene antidot lattices
We explore the consequences of electron-phonon (e-ph) coupling in graphene antidot lattices (graphene nanomeshes), i.e., triangular superlattices of circular holes (antidots) in a graphene sheet. They display a direct band gap whose magnitude can be controlled via the antidot size and density. The relevant coupling mechanism in these semiconducting counterparts of graphene is the modulation of ...
متن کاملStrain and phonon shifts in GaAs12xPx alloys
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 sam...
متن کاملIsotopic fingerprint of electron-phonon coupling in high-Tc cuprates.
Angle-resolved photoemission spectroscopy with low-energy tunable photons along the nodal direction of oxygen isotope substituted Bi(2)Sr(2)CaCu(2)O(8+delta) reveals a distinct oxygen isotope shift near the electron-boson coupling "kink" in the electronic dispersion. The magnitude (a few meV) and direction of the kink shift are as expected due to the measured isotopic shift of phonon frequency,...
متن کاملPressure measurements of TO-phonon anharmonicity in isotopic ZnS
We have measured the dependence on pressure of the line-widths of the TO and LO Raman phonons of βZnS. In order to enhance the phenomena observed, and to eliminate possible effects of isotopic disorder, we have measured a nearly isotopically pure crystal, ZnS. The strongly structured pressure effects observed are interpreted on the basis of anharmonic decay and the corresponding two-phonon dens...
