← ScienceWhich outcome occurs when compressive stress misaligns a crystal lattice?
A)Reduced electron Fermi energy results
B)Increased dislocation density accumulates, thus✓
C)Enhanced phonon mean free path
D)Elevated magnetic domain wall velocity
💡 Explanation
Increased dislocation density accumulates because compressive stress induces plastic deformation via dislocation glide, a mechanism where atomic planes slip. Therefore, dislocation density increases, rather than changes in electron energy since band structure is affected less.
