| Summary: | 碩士 === 輔仁大學 === 物理學系 === 93 === We use the Polarized Raman Scattering to find out the structure of glasses. Regarding the Raman Spectra of glass material, there is a very special peak in the low frequency, which is called“Boson peak”. Physically speaking, the origin of this low frequency peak is still an open issue. Thus in this study, we discuss this controversial issue from two new approaches, the cluster mode and the non-coincidence effect. Here we focus on the relationship between the low frequency dynamics and the intermediate order in glasses.
