Project summary

Objectives of the Project:

The objective of the Project is to develop the technologies of synthesis of novel carbon nanomaterials and composites and to fabricate efficient electron field emitters (cold cathodes) based on these materials.

As an original building nanomaterial in the synthesis of composites and coatings three types of carbon nanoparticles will be used: i) ultradisperse diamond, ii) onion-like carbon, and iii) carbon nanotubes. Nanodiamond and onion-like carbon particles will be produced by means of explosions, and carbon nanotubes will be synthesized using a dc arc technique.

Technologies for the synthesis of carbon composites and coatings will be based on the following approachs: i) shock-wave compactization of various powder materials with ultradisperse diamond, ii) explosive implantation of diamond particles into metal substrates, and iii) codeposition of metals with carbon nanoparticles in electroplating and electroless plating processes.

Complex investigations of electron field emission from carbon nanocomposites and coatings will be aimed at obtaining optimal structure of the nanomaterials and fabrication of the emitting structures which should provide long-term stability of field emission at high current densities and low electric fields. One of the priorities of the research will be the study of the nature and properties of the emission sites using a scanning tunneling-field emission microscope. As a result, efficient field electron emitters will be developed and fabricated for their potential applications in vacuum electronics devices and field emission displays technologies.

Potential role of foreign collaborators:


— participation in discussion and ellaboration of the Work Plan of the project;
— joint research works in the fields of structural analysis of carbon nanoparticles and field emission from nanocomposites.
