← ScienceWhich 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.
