Which outcome occurs when applying strong external electric field to semiconductor electron system near tunneling barrier?

💡 Explanation

When a strong external electric field is applied to a semiconductor near a tunneling barrier, field emission/lowering occurs because the electric field warps the potential barrier, making it thinner and more transparent, thus greatly increasing tunneling probability. Therefore, increased tunneling is the result, rather than suppressing interaction, enhancing repulsion, or reducing effective mass, each requiring different conditions.
