← ScienceWhich mechanism causes increased resistance when mechanical stress distorts a piezoelectric crystal?
A)Reduced piezoelectric charge generation
B)Enhanced electron-phonon scattering✓
C)Increased crystalline defect formation
D)Decreased ferroelectric domain alignment
💡 Explanation
Mechanical stress induces lattice vibrations altering electron flow; Enhanced electron-phonon scattering raises resistance. This increased scattering dissipates electron momentum because the stress creates more scattering points, therefore resistance increases rather than decreases via piezoelectric effects or defect changes.
