← ScienceWhich mechanism causes electrons in silicon to conduct current more effectively when the temperature of a semiconductor increases within a narrow range?
A)Increased electron-hole pair generation✓
B)Reduced phonon scattering influence
C)Enhanced band gap energy reduction
D)Decreased dopant ions saturation
💡 Explanation
Higher semiconductor temperatures provide enough energy to overcome the band gap energy via increased electron-hole pair generation, therefore mobile carriers increase for conduction, rather than reduced scattering; other provided situations do not influence conductivity.
