← ScienceWhich outcome results when applying pressure increasing the hopping rate in a doped semiconductor?
A)Increased electrical conductivity occurs✓
B)Band gap magnitude exhibits hysteresis
C)Intrinsic carrier concentration decreases
D)Material transforms to an insulator
💡 Explanation
Increased pressure enhances electron mobility through the 'hopping mechanism,' thus increasing conductivity, because localized states broaden into a band more readily; therefore the conductivity increases rather than decreasing it or inducing hysteresis.
