Science

Which outcome occurs when an amplifier circuit's electron temperature exceeds its lattice temperature?

A)Reduced transistor switching speed
B)Increased electron-phonon scattering
C)Enhanced quantum tunneling rate
D)Decreased average kinetic energy

💡 Explanation

Transistor speed decreases because increased electron temperature relative to the lattice causes velocity saturation within the semiconductor's channel; therefore, switching slows rather than speeding up because electrons lose energy to lattice vibrations.
