Which outcome occurs when a rapidly cooled semiconductor crystal contains dislocations?

A)Increased rate of electron-hole recombination
B)Enhanced thermal conductivity at defects
C)Increased free carrier concentration locally
D)Higher efficiency optical photon emission

💡 Explanation

Dislocations influence the band structure near defects, leading to increased electron-hole recombination rates. Recombination occurs because dislocations introduce electronic states within the band gap; therefore, electrons and holes recombine more readily, rather than maintain their individual carrier states.
