Which outcome results when a semiconductor quantum dot's wave function is tightly confined by surrounding potential energy barriers?

A)Increased transition energy between quantum states
B)Decreased Coulomb blockade effect at low bias
C)Enhanced spin coherence from reduced relaxation
D)Suppressed quantum tunneling through dielectric layers

💡 Explanation

When the wave function becomes tightly confined, the uncertainty principle dictates a larger momentum uncertainty, increasing the kinetic energy and transition energy between quantum states. Therefore, increased transition energy results, rather than the alternatives which imply reduced quantum effects from altered potential barriers.
