← ScienceWhich mechanism alters electron mobility near the graphene oxide gap?
A)Quantum confinement effects✓
B)Increased phonon scattering
C)Polaron formation enhancement
D)Increased dielectric screening
💡 Explanation
Quantum confinement effects raise the energy levels of the electrons due to the physical limitations creating a quantum dot. Therefore, electron's traverse the gap is impeded raising tunneling resistance, rather than mobility increase from enhanced dielectric screening.
