Which outcome occurs when applying pressure to piezoelectric nanocrystals?

A)Charge displacement creates electric polarization✓

B)Lattice defects increase electron mobility

C)Phonon vibrations generate heat gradients

D)Decreased band gap allows conduction

💡 Explanation

Applying pressure causes the piezoelectric effect; this mechanical stress deforms the crystal lattice. Because charge displacement creates an electric dipole moment across the crystal, therefore electrical polarization occurs, rather than increased electron mobility due to defects.
