← ScienceWhich outcome occurs when stress exceeds silicon crystal's limit?
A)Increased electron-hole pair recombination rate✓
B)Enhanced piezoelectric voltage generation
C)Decreased intrinsic carrier concentration
D)Increased band gap magnitude
💡 Explanation
Increased electron-hole pair recombination occurs due to the increased density of dislocations; increased dislocations act as trapping centers via **Shockley-Read-Hall recombination**. Therefore, recombination rate increases, rather than decreased carrier concentration, because the energy levels shift closer to mid-gap.
