FIELD: electricity.
SUBSTANCE: preparation method of a dielectric specimen for investigation on a focused-beam electronic microscope of its micro- and nanostructure involves application of a current-carrying coating onto the specimen surface and provision of electrical contact of the specimen coating with the current-carrying object table. The current-carrying coating is applied by wetting of the specimen surface with a solution of hydrophilic non-evaporable non-flammable non-toxic current-carrying ionic liquid in the form of tetrachloroferrate of N-decylpyridinium in acetone and further drying of the specimen in the air till complete removal of a volatile component.
EFFECT: prevention of accumulation of electrical charges on the surface of dielectric specimens.
