← ScienceWhat outcome arises when a metal-oxide-semiconductor field-effect transistor (MOSFET) gate voltage surpasses the threshold voltage?
A)Formation of a conducting channel✓
B)Increased gate oxide breakdown risk
C)Substrate electron-hole recombination
D)Reduced source-drain leakage current
💡 Explanation
When gate voltage exceeds the threshold voltage (Vth), channel inversion occurs because the electric field attracts charge carriers and leads to formation of a conducting channel. Therefore, a channel forms not oxide breakdown, recombination nor reduced leakage which depend on different operating regime boundaries.
