โ ScienceWhich outcome occurs when a sustained high current drives a molecular bridge?
A)Bond dissociation and molecular fragmentationโ
B)Increased conductivity due to resonant tunneling
C)Rotational alignment reduces steric hindrance
D)Quantum interference and conductance quantization
๐ก Explanation
Increased thermal energy leads to bond dissociation and molecular fragmentation because vibrational modes are excited via electron-phonon coupling โ causing the bonds to break faster than relaxation. Therefore the bridge fragments rather than conducting more efficiently under extreme load.
