Which outcome occurs when gallium arsenide LED junctions exceed forward current limits?

💡 Explanation

Thermal runaway junction destruction occurs because increased current causes enhanced electron-hole recombination leading to heat generation exceeding dissipation capabilities causing a positive feedback loop. Therefore, heat rapidly degrades operation rather than improving functionality, because material properties favor device overheating.
