← ScienceWhich outcome affects semiconductor transistor on-current when gate oxide thickness decreases?
A)Increased quantum tunneling probability✓
B)Reduced electron-phonon scattering
C)Enhanced Auger recombination rate
D)Decreased channel length modulation
💡 Explanation
Increased quantum tunneling causes higher leakage current because electrons tunnel directly through the thinner gate oxide; therefore, on-current is affected by increased tunneling, rather than reduced scattering or recombination, due to oxide thickness.
