Webb12 apr. 2024 · Raman scattering is commonly used to quantify defects in s p 2 carbons, mostly based on the values of the double-resonant D-band intensity. It is well known that this peculiar band undergoes changes when the s p 2 carbon is polished. However, the physical process behind this phenomenon is unclear so far.
