Abstract Understanding and decoupling the effects of strain and doping in graphene remains a central challenge in Raman spectroscopy, as far-field measurements inherently average local variations. In this work, we combine conventional Raman spectroscopy, tip-enhanced Raman spectroscopy (TERS), G–2D bands correlation analysis, …
