← ScienceWhich outcome occurs when a crystalline sensor exceeds doping limits?
A)Increased electron-hole recombination probability✓
B)Decreased thermal expansion coefficient
C)Increased intrinsic carrier concentration
D)Decreased resistance to mechanical stress
💡 Explanation
Exceeding doping limits enhances non-radiative electron-hole recombination through increased crystal defects. The Shockley-Read-Hall recombination mechanism becomes dominant because increased trap states enhance electron-hole interactions, therefore reducing the sensor's efficiency rather than impacting thermal or mechanical properties.
