Which 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.
