Which impact on integrated circuit performance results when thermal gradients drastically alter semiconductor crystal lattice parameters?

A)Decreased channel carrier mobility
B)Increased frequency switching ability
C)Enhanced Zener tunneling probability
D)Reduced gate oxide tunneling current

💡 Explanation

Decreased channel carrier mobility occurs because lattice parameter changes modify the band structure and introduce phonon scattering hindering electron transport: this is the electron-phonon interaction. Therefore mobility drops, rather than switching speed increasing, because mobility affects transistor drive strength.
