ABSTRACTThin films of ternary (GeS3)1−xAgx glasses (x=0.1 and 0.2) are studied in this work. Thin films are fabricated in a vacuum thermal evaporator at 3 different evaporation angles (0°, 30° and 45°). All thin film samples are examined in Raman spectroscopy. Raman results of both normally and obliquely deposited thin film samples reveal Ge-S CS modes (∼340cm−1) , Ge-S ES (∼360cm−1) modes, and thiogermanate modes Q1∼Q3 (390cm−1∼437cm−1). In addition, sharp peaks due to sulfur rings (S8) are observed at 218cm−1 and 470cm−1. Raman line-shapes of thin films are qualitatively consistent with their corresponding bulk glasses. However, the sharp peaks due to sulfur rings were not observed in bulk glasses. By comparing CS modes of thin films of three angles, we observe that normally deposited (0 degree) thin film shows a red-shift in center and a broadening in width. The film thickness of normally deposited films are significantly smaller comparing with that of corresponding obliquely deposited films.

Band Position

Isotropic Raman line shapes of simple molecular fluids exhibit critical line broadening near their respective liquid-gas critical points. In order to observe this phenomenon, it is essential that the band position of a given vibrational mode is density-dependent, and that vibrational depopulation processes negligibly contribute to line broadening. Special attention was given to the fact that the isotropic (i.e., nonrotationally broadened) line shape of liquid N2 is affected by resonant intermolecular vibrational interactions between identical oscillators. By means of the well-chosen isotopic mixture (14N2).975 - (14N15N).025, the temperature and density dependences of shift, width, and asymmetry of the resonantly coupled 14N2 and, depending on the S/N ratio available, of the resonantly uncoupled 14N15N were determined, with up to milli-Kelvin resolution, in the coexisting liquid and gas phases and along the critical isochore, using a highest-resolution double monochromator and modern charge-coupled device detection techniques. Clear evidence was found that vibrational resonance couplings are present in all dense phases studied.
