← ScienceWhich outcome occurs when high static stress disrupts a crystal lattice?
A)Decreased material dielectric breakdown strength✓
B)Increased speed of sound propagation
C)Reduced electron-hole recombination efficiency
D)Enhanced ferromagnetic coercivity
💡 Explanation
Applied stress distorts the atomic spacing in the crystal structure, facilitating easier electron tunneling via Frenkel defects and vacancy formation thereby increasing electron flow across the material. This is because dielectric breakdown strength is reduced with increased defect densities. Therefore, the answer is decreased dielectric strength, rather than increased ferromagnetic coercivity.
