The molecular structure of advanced materials such as graphene, carbon nanotubes, and diamond-like carbon coatings is critical to their performance. Raman spectroscopy probes these structures, for example distinguishing single- and double-layer graphene through differences in the 2D band. Tetrahedral carbon introduces structural defects but also generates distinct Raman peaks. WP 532 nm Raman systems are commonly used for graphene, carbon nanotubes, and related materials, but impurities in technical samples can cause strong fluorescence, making effective fluorescence rejection essential for high-quality spectra.
In silicon, stress and strain produce measurable shifts in Raman bands, requiring high spectral resolution and a stable frequency axis to accurately resolve changes in peak shape and position. Doping and chemical vapor deposition layers are identified through their characteristic spectral signatures, and the small laser spot enables mapping of local doping levels and their spatial variation across the surface.
