← ScienceWhich mechanism underlies zero resistance when thin-film niobium nitride is approaching absolute zero?
A)Cooper pairing formation✓
B)Electron-phonon scattering slowdown
C)Fermi level hybridization
D)Quantum Hall edge state propagation
💡 Explanation
Forming a superconducting state arises because decreasing temperatures allows Cooper pairing formation, therefore electron pairs propagate without scattering thereby resulting in zero resistance, rather than simple slowing interactions.
