Which risk increases when gallium arsenide has lattice defects?

A)Auger recombination suppresses light emission
B)Increased piezoelectric behavior under stress
C)Ferromagnetic domains spontaneously start aligning
D)Thermal conductivity becomes size quantized

💡 Explanation

Lattice defects introduce energy states within the band gap, providing pathways for non-radiative recombination. This occurs due to Auger recombination, because excited electrons lose energy to other electrons, rather than emitting photons; therefore luminescence diminishes with more defects, rather than other band structure effects.
