Description
A mathematical model of the electrode surface morphology was proposed and
constructed, considering submicron irregularities on its surface. It is shown that the
theoretical decrease in the field electron emission current density with an increase
in the electron yield work from the metal does not agree well with the breakdown
field experiments for different materials. It is shown that the presented model of
the metal surface makes it possible to simulate the field emission current and to
agree the theoretical model with the experimental results.
