Which consequence results when electron's confinement decreases within a quantum dot?

A)Energy level spacing decreases
B)Coulomb blockade becomes more pronounced
C)Quantum capacitance decreases sharply
D)Electron-phonon scattering rate increases

💡 Explanation

Decreased confinement allows the electron's wavefunction to spread into larger space. This reduces the energy quantization through the particle-in-a-box model; the electron energy levels become closer because energy is inversely proportional to space. As confinement goes down energy goes down therefore other options are less appropriate.
