“…The surface penetration depth of the laser light that we employed is estimated to be of the order of 10 2 Å because we are operating well above the band gaps of these semiconducting compounds ͑see Table I͒. Thus we have considered the possibility that the Raman signal is caused either by elemental antimony [25][26][27] or antimony oxides. 28,29 We have therefore measured the Raman signal from a piece of high- purity antimony, Sb.…”

Lett. 92, 203508 (2008); 10.1063/1.2936298 Two-dimensional photonic crystals in antimony-based films fabricated by holography -earth ions occupy the voids in the skutterudite structure. These void-filling ions interact with some of the lattice vibrations in this structure and produce a shift and broadening of the observed lines. The most prominent lines in all of the samples are the Sb 4 ring-breathing modes.

Measurements are reported for optical phonons (k = 0) by Raman scattering at 300, 80, and 2 I ( for Bi, Cd, Mg, and Zn. The linewidths are found to increase, and the frequencies t~ decrease, as the temperature is raised. The temperature dependent portion of the linewidth is attributed t o a two-phonon decay process. In addition, the contributions to the linewidth from the isotope effect, the electron-phonon interaction, and strains are disoussed.
