← ScienceWhich risk increases when silicon crystals contain impurities?
A)Increased avalanche breakdown susceptibility✓
B)Decreased thermal runaway resistance
C)Increased minority carrier lifetime
D)Decreased electron mobility effects
💡 Explanation
Avalanche breakdown susceptibility increases because, with impurities, impact ionization gains dominance at lower voltages, therefore breakdown occurs sooner rather than intrinsic material threshold; this is due to increased carrier concentrations.
