Which outcome occurs when critical point defects alter semiconductor band gap?

A)Reduced threshold voltage in MOSFETs
B)Increased Hall effect sensitivity
C)Improved thermoelectric conversion efficiency
D)Enhanced chemical reaction catalytic activity

💡 Explanation

The introduction of point defects creates intermediate energy levels within the band gap, influencing the Shockley-Read-Hall recombination. This lowers the effective threshold voltage because less energy is required for transistor switching, therefore threshold reduces rather than affecting other device characteristics.
