Raman Mapping Analysis. In the example shown the lactose and sucrose particles were measured to be 49 21 µm and 44 15 µm respectively. This was in agreement with the particle sizes of the raw materials measured via light scattering and the final crystal sizes observed under.
Analysis of the Raman G and 2D peak p. Raman spectral imaging or mapping is a method for generating detailed chemical images based on a samples Raman spectrum. Raman mapping and imaging analysis provides a spectral image with consistent resolution of 200 nanometers.
Water does not generally interfere with Raman spectral analysis.
The hypercube is analysed to produce Raman images. We present a Raman mapping study of monolayer graphene G and 2D bands after integration on silicon strip-waveguide-based micro-ring resonators MRRs to characterize the effects of the graphene transfer processes on its structural and optoelectronic properties. At right the spectral sources with their percentages and at left the corresponding maps 9. Analysis of the Raman G and 2D peak positions and relative intensities reveal that the graphene is electrically intrinsic where it is suspended over the MRR but is moderately hole-doped where it sits on top of the waveguide structure.
