← ScienceWhich outcome compromises LED forward voltage under high current?
A)Reduced radiative recombination efficiency greatly✓
B)Increased band bending effect exists
C)Enhanced electron-hole symmetry emerges
D)Elevated phonon scattering effect increases
💡 Explanation
Reduced radiative recombination arises with high current density because Auger recombination increases sharply which reduces light output efficiency, therefore voltage performance suffers, rather than enhanced emission, because other pathways dominate de-excitation.
