← ScienceWhich consequence results when an electron exceeds its *Fermi level* in a *metal-oxide-semiconductor field-effect transistor* (MOSFET)?
A)Hot-carrier injection becomes more likely✓
B)Substrate current exhibits total quenching
C)The channel capacitance reaches minimum
D)Threshold voltage remains completely stable
💡 Explanation
Hot-carrier injection increases because electrons with energy above the Fermi level can overcome potential barriers and enter the gate oxide. Therefore, hot-carrier injection probability increases, rather than alternative effects which require a specific voltage bias.
