Which consequence results when quantum tunneling dominates oxide breakdown?

A)Gate oxide dielectric breakdown
B)Increased channel carrier mobility
C)Reduced short channel effects
D)Improved subthreshold swing limits

💡 Explanation

Gate oxides become thin; electron tunneling induces oxide breakdown because Fowler-Nordheim tunneling increases leakage current, creating defects which compromise insulating ability; therefore, dielectric breakdown occurs rather than enhancing transistor performance under normal switching.
