← ScienceWhich consequence results when a quantum dot undergoes dielectric breakdown?
A)Increased rate of electron tunneling✓
B)Suppressed rate of spin decoherence
C)Decreased Coulomb blockade effect
D)Enhanced quasiparticle interference pattern
💡 Explanation
Dielectric breakdown creates conductive pathways, allowing more electrons to tunnel through the barrier due to increased quantum mechanical transmission probability via **direct tunneling*; therefore, higher current leaks result, rather than reduced tunneling rates or altered quantum phenomena in stable dots.
