← ScienceWhich outcome frequently results when a nanoscale MOSFET device is aggressively scaled down?
A)Increased gate leakage current✓
B)Reduced channel mobility occurs
C)Enhanced subthreshold swing behavior
D)Improved transconductance performance
💡 Explanation
Increased gate leakage current negatively impacts performance because quantum tunneling allows electrons to penetrate the gate dielectric. This is undesirable, therefore this effect will dominate rather than enhance performance, unlike the other options under these conditions.
