← ScienceWhich mechanism influences semiconductor breakdown when increasing ambient temperature narrows gaps?
A)Impact ionization causes avalanche multiplication✓
B)Zener tunneling allows electron conduction
C)Resonant tunneling inhibits current flow
D)Doppler broadening increases energy dispersion
💡 Explanation
Impact ionization causes semiconductor breakdown through avalanche multiplication because higher temperatures reduce the band gap; therefore, lower energy is needed to liberate electrons and create further carriers, rather than Zener tunneling requiring higher voltages.
