← ScienceWhich outcome results when dopants cause increased electron flow in semiconductors?
A)Increased conductivity and reduced bandgap✓
B)Decreased resistivity and phonon scattering
C)Enhanced capacitance and magnetic domains
D)Augmented piezoelectricity and ionic diffusion
💡 Explanation
Increased mobile electron (or hole) concentration resulting from doping encourages increased conductivity, because donor/acceptor doping adds energy states close to the conduction band, resulting in smaller bandgap needing less energy for electrons to jump across, therefore conductivity goes up, rather than causing changes in other physical parameters.
