Which mechanism limits electron mobility along graphene grain boundaries?

💡 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.
