Which electrical behavior occurs when a semiconductor’s impurity increases?

💡 Explanation

Increased impurity concentration enhances doping, augmenting the free carrier generation via band bending. This increases conductivity because the availability of electrons or holes is elevated rather than decreasing the band gap, changing resistance, or inhibiting phonon scattering.
