Which consequence results when electrons encounter oxide layers?

💡 Explanation

Oxide layers normally insulate, therefore electrons experience quantum tunnelling and conductivity increases because electron wave functions penetrate the classically forbidden region, rather than perfect blockage if tunnelling was absent; this decreases resistance.
