Which outcome results when contaminants enable quantum tunneling in transistors?

A)Increased gate leakage current occurs✓

B)Substrate depletion region width increases

C)Channel mobility increases substantially

D)Threshold voltage becomes more stable

💡 Explanation

Increased gate leakage results because contaminants create unintended potential wells facilitating quantum tunneling through the gate dielectric. Therefore, gate current increases, rather than leading to better transistor performance via mobility enhancement or threshold voltage stability; other regions are unaffected.
