← ScienceWhich consequence results when a silicon-dopant's p-orbital mismatch occurs in a gallium arsenide semiconductor?
A)Reduced electron-hole recombination efficiency
B)Increased phonon scattering events
C)Decreased Hall effect coefficient
D)Increased non-radiative carrier recombination✓
💡 Explanation
Increased non-radiative carrier recombination results, because energy dissipates as heat via surface defects, rather than light emission relying on properly aligned orbitals for efficient radiative transitions. Therefore, luminescence diminishes, rather than other effects related to specific doping levels.
