Which mechanism causes high electrical resistance in intrinsic semiconductors?

💡 Explanation

Low conductivity occurs because intrinsic materials have a small carrier population; the Fermi level sits within the band gap causing minimal electron density near band edges. Therefore, conductivity is low, rather than dominated by scattering mechanisms that affect mobility in doped semiconductors.
