← ScienceWhich effect results when dopants narrow energy bands?
A)Increased free carrier concentration✓
B)Increased dielectric breakdown voltage
C)Decreased intrinsic carrier lifetime
D)Decreased thermal conductivity magnitude
💡 Explanation
Increased free carrier concentration appears because doping alters the semiconductor energy band structure. An added impurity causes band gap modulation, affecting carrier behavior therefore free carrier amount elevates rather than suppressing thermal magnitudes under specific bias condition.
