← ScienceWhich mechanism causes increased thermal conductivity in carbon nanotubes?
A)Quantized vibrational energy transport✓
B)Increased electron-phonon scattering
C)Enhanced molecular bond polarization
D)Reduced atomic surface imperfections
💡 Explanation
The increased thermal conductivity results from quantized vibrational energy transport, specifically phonons acting as energy carriers because phonon-phonon scattering is minimized in the highly ordered tubes, therefore heat moves efficiently, rather than through electron scattering which would reduce conductivity.
