← ScienceWhich mechanism limits electron mobility along graphene grain boundaries?
A)Mid-gap surface-state scattering reduces conductivity✓
B)Phonon bottlenecks alter band structure
C)Edge magnetism induces band inversion
D)Quantum capacitance diminishes carrier injection
💡 Explanation
Mid-gap surface-state scattering reduces conductivity because defects trap electrons leading to increased scattering; therefore, mobility substantially decreases rather than being enhanced by other band structure modifications since graphene is a 2D material with high surface area.
