Abstract
We have studied transient processes of the thermal ionization of sodium on the surface of NaAuy 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 NaAuy film, while the efficiency of thermal ionization of Na atoms is related to the concentration of holes near the NaAuy/vacuum interface.
