The G and 2D Raman bands exhibit similar pressure slopes for both PTM irrespectively of any unintentional initial doping and/or strain of the samples. Our analysis suggests that any pressure-induced charge transfer effects are negligibly small to influence the pressure response of graphene. This is determined by the mechanical stress due to the pressure-induced substrate contraction and","authors_text":"C. Galiotis, D. Christofilos, G. Kalosakas, J. Arvanitidis, J. Parthenios, K.
