← ScienceWhich phenomenon arises when dopant atoms disrupt silicon lattice periodicity?
A)Decreased minority carrier recombination lifetime
B)Increased probability of Umklapp scattering✓
C)Formation of Schottky junction barrier
D)Enhanced intrinsic carrier concentration
💡 Explanation
Umklapp scattering increases due to the disruption of lattice periodicity by dopant atoms, making momentum conservation less restrictive. Phonon-electron scattering pathways rise because of this lattice distortion; therefore Umklapp scattering increases rather than lower recombination rates under equilibrium.
