Which consequence results when rapid electron transfer exceeds electron mobility?

A)Increased dielectric breakdown strength
B)Increased device operating lifetime
C)Hot carrier injection into gate oxide
D)Improved transistor switching performance

💡 Explanation

Hot carrier injection occurs because acceleration from the electric field leads to higher electron kinetic energy; therefore, highly energetic electrons enter the gate oxide, rather than contributing to normal conduction, due to limited mobility.
