← ScienceWhich mechanism impedes electron flow when crystal lattice defects increase?
A)Increased phonon scattering✓
B)Enhanced electron tunneling
C)Magnon-electron interaction
D)Increased polaron formation
💡 Explanation
Increased crystal lattice defects cause increased *phonon scattering*, where lattice vibrations disrupt electron movement. Because electrons collide more frequently with the lattice, there is greater resistivity and thus a disruption, rather than tunneling or increased quasiparticle behaviors.
