← ScienceWhich risk significantly increases when doping a silicon crystal?
A)Increased electron mobility and saturation
B)Augmented probability of Auger recombination✓
C)Decreased bandgap energy and resistivity
D)Prolonged Shockley-Read-Hall recombination lifetime
💡 Explanation
Doping enhances electron-hole pair creation, increasing the odds for Auger recombination because energy from electron-hole recombination is transferred to another electron. Therefore, the Auger effect becomes more probable rather than SRH decreasing, without directly addressing either electron mobility or affecting bandgap specifically.
