Recommended application field: - fied emitters; - probes for scanning tunneling microscopy and nanotechnology; - microsurgical instruments with qualitative changes of roughness level.

Advantages over analogues: - formation of surface with a zero-level roughness (atomically smooth metal surface); - high degree of localization of field emission; - atomic sharpness of STM probes; - reducing traumatic effects of microsurgical instruments.

The development stage readiness: Tested experimental exploitation order

Description of the development:
()
Various mobifications of the method of evaporation in high electric fields are the most promising methods of forming surface of different nanometer-scale objects. However, the main obstacle to the use of this method is super high electric feld on a surface of a processed object. In such fields there are serious technological problems connected with destruction of objects under theinfluence of mechanical stress generated by the fields. We propose to use phenomenon of high-field evaporation of metals in dielectric liquids at low temperatures. This phenomenon was revealed and studied by our team together with University of Surrey Shool of Electronic (Surrey, UK) and Hahn-Meitner-Institute (Berlin, Germany). This phenomenon and process of field evaporation in active gases could be used for controlled forming of metal objects with sizes in a nanometer range. The magnitude of electric fields below the of field evaporation in high vacuum is required for realization of high-field evaporation of metals in dielectric liquids. This opens up technological use of this phenomenon.
