Which outcome occurs when forward voltage polarity reverses on GaN LEDs?

A)Rapid device overheating occurs
B)Increased photon emission efficiency
C)Reduced depletion region width
D)Stabilized electron-hole recombination

💡 Explanation

Reversed polarity causes excessive current flow through the low resistance path because the *breakdown effect* overcomes doping limitations, leading to rapid heat generation and failure; therefore, overheating occurs rather than increased light emission or depletion region changes because forward bias is needed.
