Project summary

For the achievement of posed task the following explorations will be carried out:
(1) The elaboration of the technology of the synthesis of carbon structures with high concentration of nanotubes, with their tips oriented normally to the plane of the substrate. For the synthesis of nanotube carbon structures the series of methods will be used, including:

- methods of the pyrolisis of polyethylene and heptane;
- method of the magnetron sputtering of carbon;
- method of fabrication of carbon structures with oriented nanotubes from carbon nanotubes suspension by means of special filters;
- method of the sputtering of carbon in the contact arc.

(2) The investigation of the structure of fabricated carbon layers by following methods of microscopic and spectroscopic analysis:

- transmission high resolution electron microscopy (HREM);
- scanning electron microscopy (SEM);
- scanning tunneling microscopy (STM);
- X-ray emission spectroscopy (XES).

(3) The investigations of field electron emission from nanotube carbon structures:

- investigations of the surface composition of nanotube carbon structures by the method of Auger spectroscopy;
- investigations and analysis of current-voltage characteristics of field emission from nanotube carbon structures in ultrahigh and high vacuum environment;
- investigations of the work function of nanotube carbon structures;
- investigations of time stability and the spatial distribution of emission current;
- search for correlation between emission characteristics and parameters of nanotube carbon structures and the determination of the optimal parameters of structures for construction on their basis of low voltage electron emitters.

(4) Theoretical investigations of the electron spectra and the conditions of growth of carbon nanotubes and also the field electron emission from nanotube carbon structures:

- calculations of the electric field strength near the surfaces of field emitters made on the base of nanotube carbon structures;
- calculations of the potential of ionization and the work function of carbon nanotubes;
- theoretical explorations of the conditions of growth of carbon nanotubes with open ends.

Expected results

It is expected that, as a result of carrying out of the Project, planar nanotube carbon structures with aligned sticking out nanotubes will be developed and on their basis low voltage field electron emitters will be created, applicable for use in the flat low voltage vacuum displays of high brightness. Carried out explorations will allow to start the development of novel flat low voltage vacuum displays characterized by appreciably less weight, size and the level of X-ray emission excited by an electron beam, compared to traditional displays.

The achievement of these tasks will be based on the experience that has been accumulated by the participants of the Project in the field of fabrication of nanotube carbon materials, in the field of structural analysis of solids, and in the field of the developments of electron emitters of various kinds.

The Project supposes the employment in its performance of the big group of scientists and engineers associated with the development of elements of control systems for transportation of mass-destruction weapon.
