Doping effects on exfoliated graphenes induced by methyl orange (MO) have been studied by spatially resolved Raman spectroscopy. When the MO molecules were adsorbed on the top of graphenes, the charge transfer between them caused two outcomes simultaneously. One is the strong chemical doping in grap...
