We have studied transient processes of the thermal ionization of sodium on the surface of NaAu_ y semiconductor film under the action of a variable external electric field. It is established that the kinetics of Na^+ ion current during variation of the external field is determined by the establishment of charge distribution in the NaAu_ y film, while the efficiency of thermal ionization of Na atoms is related to the concentration of holes near the NaAu_ y /vacuum interface.
