Some changes of the activation energy el 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 el is found for shallow donor concentrations of about
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
