← ScienceWhich constraint becomes paramount when doping a semiconductor crystal?
A)Maintaining overall charge neutrality✓
B)Maximizing carrier scattering rate
C)Increasing crystal's optical absorption
D)Balancing electron-phonon interactions
💡 Explanation
Maintaining charge neutrality dominates crystal doping because the mechanism of electrostatic equilibrium opposes any significant net charge imbalance; therefore, electrons/holes rearrange rather than allowing significant localized charge accumulation that would destabilize the crystal.
