Which outcome occurs when defects alter silicon LED's band?

A)Recombination lowers light-emission efficiency
B)Increased conductivity enhances radiative output
C)Blue-shift raises peak light frequency
D)Phosphorescence causes sustained afterglow emission

💡 Explanation

Increased lattice defects create energy states within the band gap, thereby, increasing electron-hole recombination, lowering radiative emission; therefore, LEDs produce less light rather than enhanced emission because defects act recombination centers.
