← ScienceWhich outcome occurs when a voltage induces piezoelectricity in a crystal sensor?
A)Mechanical strain produces charge separation✓
B)Temperature gradient induces phonon blocking
C)Thermal expansion stabilizes the structure
D)Quantum tunneling induces ohmic conductivity
💡 Explanation
Mechanical strain produces charge separation because the lattice deforms, altering dipole moments within the crystal structure due to the piezoelectric effect. Therefore, the mechanical action yields a voltage rather than phonon blocking or quantum tunneling, associated with thermal or high-field scenarios.
