← ScienceWhich consequence results when surface electron mobility exceeds limit?
A)Increased short-channel effect degradation✓
B)Improved subthreshold slope behavior
C)Reduced gate oxide tunneling current
D)Suppressed parasitic bipolar amplification
💡 Explanation
Increased channel doping causes mobility degradation because increased scattering reduces the electron's average velocity, therefore the short-channel effect increases rather than improving subthreshold behavior, because high doping affects the bulk electric field.
