Which outcome occurs when imperfections alter silicon's band structure?

A)Reduced carrier mobility and conductivity
B)Increased thermal energy dissipation
C)Enhanced electron-phonon scattering rates
D)Augmented second harmonic generation efficiency

💡 Explanation

Reduced carrier mobility and conductivity results from the changed band structure; because impurities cause **impurity scattering** which lowers electron velocity and increases resistance. Therefore, conductivity drops, rather than phonon scattering increasing or harmonic generation, under bias.
