Which phenomenon limits electron escape current when applying strong external field?

💡 Explanation

Reducing external field narrows the wave function and permits quantum tunneling through the potential barrier; electron escape is limited because the barrier width determines the tunneling probability; therefore, tunneling limits escape, rather than a supply issue from high temperature or charge effects.
