electron model
     
         A {model} of {semiconductor} behaviour in which
        {donors} contribute the {charge} of an {electron}, and
        {acceptors} contribute a space for same, in effect
        contributing a fictional positive charge of similiar
        magnitude.  Physicists use the {electron model}.  Some
        language theorists consider language and the {electron} to be
        {model}s in themselves.
     
        Contrast {hole model}.
