← ScienceWhich outcome occurs when electrons cool a metallic nanowire?
A)Increased phonon population and heat transfer✓
B)Decreased electrostatic repulsive forces overall
C)Increased electron-phonon coupling efficiency
D)Decreased Fermi level, affecting conductivity
💡 Explanation
Increased phonon population resulting in added heat transfer appears, because cooling induces electron interactions that convert energy into lattice vibrations via electron-phonon coupling. Therefore, energy moves and creates phonons; rather than any change to static forces or band structure changes from doping effects.
