← ScienceWhich consequence results when silicon's band gap collapses?
A)Substantial current thermal runaway occurs✓
B)Increased piezoelectric charge generation results
C)Exciton formation facilitates quantum tunnelling
D)Increased free carrier recombination lifetime occurs
💡 Explanation
Current runaway results from reduced resistivity. Avalanche multiplication releases significantly increased free electrons because diminished *band gaps* exponentially reduce resistivity; therefore thermal runaway occurs rather than regulated functionality or enhanced conductivity.
