Which phenomenon occurs when the Fermi level lies within the conduction band of a doped semiconductor at cryogenic temperatures?

💡 Explanation

Enhanced electrical conductivity occurs because increased doping causes the Fermi level to enter the conduction band, via **band filling**, this increases available charge carriers. Therefore conductivity increases accordingly, rather than electron-hole recombination dominating it due to low thermal energy.
