AbstractRaman scattering experiments on high quality ZnGeP2 single crystals grown by the seeded horizontal dynamic gradient technique have been carried out. Polarized Raman spectra were obtained in the backscattering geometry at both room and low temperatures for several crystal orientations and compared with group theoretical predictions. Raman spectra from as-grown and annealed samples display distinctive differences which were explored by utilizing two different excitation wavelengths: 514.3 nm and 632.8 nm; the observed differences are attributed to a surface interdiffuasion effect.

This paper describes a detailed analysis of the dependence of Raman scattering intensity on the polarization of the incident and inelastically scattered light in PbSc 0.5 Nb 0.5 O 3 (PSN) single crystals and epitaxially compressed thin films grown on (100)-oriented MgO substrates. It is found that there are significant differences between the properties of the crystals and films, and that these differences can be attributed to the anticipated structural differences between these two forms of the same material. In particular, the scattering characteristics of the oxygen octahedra breathing mode near 810 cm-1 indicate a ferroelectric state for the crystals and a relaxor state for the films, which is consistent with the dielectric behaviors of these materials.

Increasing Temperature

Results of a polarized Raman scattering study of single crystal lithium hydrazinium sulfate, LiN2H5SO4, over a temperature interval from 11 to 300 K are discussed. Unusual temperature dependence of the band center scattering intensity is observed in a few intramolecular hydrazinium modes, intramolecular sulfate ion modes, and lattice modes. The intensity of these modes increases with increasing temperature from 11 K to about 175 K, then abruptly decreases over a small interval between 175 and 200 K. Above 200 K the band center intensity then exhibits normal behavior, slowly decreasing with increasing temperature. Possible explanations for this anomalous behavior are discussed. Key words: lithium hydrazinium sulfate, proton conductor, Raman spectroscopy.
