Which mechanism causes diminished photoconductivity when doped semiconductors reach high impurity concentrations?

💡 Explanation

Anderson localization reduces the mean free path and electron mobility as disorder increases in the semiconductor band structure; because high doping introduces such disorder, the additional charge carriers contribute less to photoconductivity, therefore reducing overall response rather than enhancing it.
