← ScienceWhich outcome occurs when nitrogen impurities disrupt the lattice of gallium arsenide semiconductors?
A)Reduced electron mobility throughout the crystal✓
B)Increased thermal conductivity properties locally
C)Amplified piezoelectric effect exhibited fully
D)Enhanced intrinsic semiconductor carrier concentration
💡 Explanation
Nitrogen impurities create lattice defects that act as scattering centers; because these centers impede electron flow via phonon scattering, overall electron mobility decreases rather than enhances carrier concentration, therefore reducing functionality rather than increased conductivity in certain areas.
