← ScienceWhich outcome reliably occurs because of quantum confinement?
A)Band gap energy increases✓
B)Electron mobility decreases linearly
C)Debye length remains unaffected
D)Superconductivity becomes exponentially suppressed
💡 Explanation
Quantum confinement increases momentum uncertainty, raising kinetic energy because momentum is inversely proportional to box size via the Heisenberg Uncertainty Principle; therefore a band gap increases rather than mobility decreasing or superconductivity changing because they rely on other effects.
