Which consequence results when dopants distort a semiconductor's crystal lattice?

A)Increased free carrier recombination rate
B)Enhanced intrinsic charge carrier mobility
C)Stabilized extrinsic semiconductor resistivity
D)Reduced temperature dependence of conductivity

💡 Explanation

Increased free carrier recombination rate occurs, specifically Shockley-Read-Hall recombination, because lattice distortion increases defect states. Therefore, carriers recombine more easily rather than contributing indefinitely to conductivity because dislocations act as recombination centres.
