Raman spectroscopy experiments show that the interaction between electrons and phonons in graphene resembles the Dirac fermion–photon coupling in quantum electrodynamics. In the early days of ...

Raman spectroscopy further confirmed the presence of graphene-like structures, showing characteristic peaks for disordered and sp2-bonded carbon. However, the researchers noted that while the ...

Definition:Raman Spectroscopy is a sophisticated analytical technique used to observe vibrational, rotational, and other low-frequency modes in a system. This material characterization technique ...

Qi and her colleagues used advanced techniques, including photoluminescence (PL) mapping and Raman spectroscopy, to analyze how fluorination changes graphene's structure and optical properties.

Our instrument is especially optimized for fast hyperspectral imaging of complex samples and materials, where a full Raman spectrum is collected at every pixel. This technique, combined with advanced ...
