Which outcome impairs nanoscale transistor performance due to a narrowed energy band?

💡 Explanation

Increased quantum tunneling results because thinner barrier widths in a transistor cause electrons to tunnel through the gate oxide due to reduced energy band, affecting proper switching; therefore, performance is hindered, rather than enhanced scattering, improved recombination rate, or inhibited thermal injection.
