WebThe formation of nanoparticles and the mechanism of their formation in a blend of a thermotropic liquid crystalline polyester (LCP) and the zinc salt of a lightly sulfonated polystyrene ionomer (Zn-SPS) were investigated using Fourier transform infrared (FTIR), thermogravimetric analysis (TGA), and gas chromatography–mass spectroscopy … WebA convenient method to study crystallinity of silicon materials is to analyze Raman scattering spectra. Crystalline silicon has one sharp peak at ~524 cm-1, but amorphous silicon has broad Raman band centered at 480 cm-1. In the case of polycrystalline silicon the Raman peak gets broader than that of c-Si and is shifted to 517 cm-1 [10].
