← ScienceWhich outcome occurs when an excited-state electron’s wave function penetrates into a forbidden region in a quantum dot?
A)Resonant tunneling through the barrier✓
B)Increased quantum dot energy levels
C)Enhanced electron-phonon coupling strength
D)Suppressed quantum confinement effect
💡 Explanation
Resonant tunneling occurs as the electron’s wave function overlaps energy states outside the quantum dot; because quantum tunneling transmits electrons through energy forbidden regions, therefore electrons escape easier, rather than remain confined affecting quantum energy.
