← ScienceWhich consequence results when increased grain boundaries affect semiconductor material bands?
A)Increased electron-phonon scattering occurs✓
B)Improved thermal vibration stability
C)Reduced electron-hole recombination events
D)Enhanced long-range magnetic ordering
💡 Explanation
Increased grain boundaries introduce more defects; therefore, the increased disorder enhances electron-phonon scattering because the periodicity of the crystal lattice is disrupted, leading to more interactions, rather than improved stability.
