← ScienceWhich outcome increases when electron energy approaches quantum well band gaps?
A)Resonant tunneling probability
B)Increased thermal conductivity
C)Decreased material hardness
D)Phonon scattering event rates✓
💡 Explanation
Increased energy causes higher phonon occupation numbers; therefore electron-phonon interactions rise via Fermi's Golden Rule, scattering electrons. This mechanism reduces mean free paths, rather than resonant transmission allowed only within the band, increasing thermal conductivity, or affecting hardness.
