This image depicts the structural origins of ‘defect peaks’ in the X-ray photoelectron spectroscopy (XPS) and Raman spectra of carbon materials. The present study reveals that these historically ambiguous peaks originate from specific atomic-level structures, such as ether-like oxygen configurations (C–O–C) and non-hexagonal rings within the carbon lattice.
