← ScienceWhich mechanism causes increased graphene conductivity contacting an electrolyte?
A)Electron doping from hydroxyl dissociation✓
B)Phonon scattering with high temperatures
C)Electron annihilation reducing resistance
D)Capacitive coupling lowering voltages
💡 Explanation
Graphene conductivity increases due to electron doping; Hydroxyl groups from dissociated water molecules donate electrons via oxidation/reduction. Electron doping enhances conductivity, rather than scattering, because coupling/annihilation would require extreme conditions and different specific experimental setups.
