Which outcome impairs transistor switching in semiconductors when thermal load changes band structure?

💡 Explanation

Reduced carrier concentration limits switching speed because increased thermal energy induces band gap narrowing via electron-phonon interactions, therefore reducing electron availability rather than enhancing scattering or tunneling, which requires different conditions.
