Abstract

Some changes of the activation energy ϵ₁ of the conductivity of Ge which are produced by variations of the compensation ratio K are studied in the region of temperatures where the conductivity is related to electrons released from shallow donors into the conduction band. A substantial increase of ϵ₁ is found for shallow donor concentrations of about 1 × 10¹⁶ cm⁻³ and 1 – K → 0. This finding is in good quantitative agreement with the theory of Shklovskii and Efros.
