← ScienceWhich electronic behavior occurs in a doped semiconductor crystal?
A)Increased free carrier concentration increase✓
B)Enhanced crystal lattice phonon resonance
C)Decreased thermal conductivity uniformity
D)Accelerated intrinsic material degradation
💡 Explanation
Doping introduces impurities that affect the band structure via increased free carrier concentration because the shallow donor/acceptor states facilitate easier excitation of electrons/holes across the band and enhanced conductivity therefore occurs rather than changes in phonons or degradation.
