← ScienceWhich outcome occurs on a doped semiconductor lattice subjected to thermal stress?
A)Decreased electron mobility due to phonon scattering✓
B)Increased electron-hole recombination from Auger
C)Enhanced piezoelectric charge displacement in crystal
D)Accelerated electromigration causing circuit failure
💡 Explanation
Decreased electron mobility occurs because increased temperature amplifies *phonon scattering*, disrupting electron flow; therefore, electron mobility decreases, rather than increasing it from other phenomenon in the complex system.
