← ScienceWhich consequence results when excessive lattice defects cause band tailing?
A)Increased non-radiative electron-hole recombination✓
B)Enhanced free carrier concentration
C)Reduced phonon scattering rate
D)Decreased material tensile strength
💡 Explanation
Increased structural disorder causes *Urbach tailing*, broadening band edges because localized states appear within the band gap; therefore non-radiative recombination increases, rather than free carriers, which is only a secondary effect at higher temperatures.
