Which outcome occurs when increasing temperatures disrupt dopant atom placement within a semiconductor?

A)Increased electron-hole recombination efficiency
B)Expansion of Bloch electron wavepackets
C)Decreased quantum tunnelling probability
D)Enhanced Debye phonon scattering rates

💡 Explanation

Increased temperature and atom displacement enhances electron-hole recombination efficiency because the Shockley-Read-Hall recombination mechanism is more effective, thus decreasing carrier lifetime. Therefore, recombination increases rather than decreasing quantum tunneling; different mechanisms dominate at high temperatures under crystal defects.
