from The Free On-line Dictionary of Computing (8 July 2008)

electron model

   <electronics> 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
   {models} in themselves.

   Contrast {hole model}.
