← ScienceWhich mechanism causes increased resistance when nitrogen impurities distort a copper crystal lattice?
A)Decreased electron mean free path✓
B)Increased electron group velocity
C)Reduced electron-phonon scattering
D)Enhanced Bloch wave propagation
💡 Explanation
Increased Nitrogen introduces defects that disrupt periodicity; therefore, the dominant mechanism is scattering centers reducing the electron mean free path because electrons collide more frequently leading to greater electrical resistance rather than increased conductivity.
