Which outcome occurs when a doped semiconductor's crystal lattice contains excessive impurities?

💡 Explanation

Decreased carrrier mean free path results because increased impurities introduces more scattering centers for electrons; this is known as Impurity Scattering. Therefore, the electrons collide more frequently, rather than traveling unimpeded; suppressed tunneling or similar only effects carrier transport at interfaces.
