Abstract
The method for controlling the migration of an electronegative chemical species within a solid substrate which exhibits ionic conduction consists in irradiating the substrate with electrons which have sufficient energy to penetrate into the substrate and to produce therein metastable excited negative ions of said species and in applying to said substrate an electric field having a direction opposite to the desired direction of migration.
