| Abstract | The report contains the results of research of carbon materials surface microrelief (piro-graphite PG-1 and highly strong reactor graphite MGP-6) with the help of air scanning tunneling microscope. The experimental carbon materials were irradiated by heavy ions of middle and high energies. The purpose of the experiments was to find out possibilities of utilization of radiation technologies for production effective multi-tips flat cathodes on the basis of field electron emission. It is known the need in such cathodes is quite big in vacuum microelectronics, for example. In flat matrix display screens production, highly efficient light sources production, etc. In the process of experiments different radiation parameters were used: the type of bombarding ions, flow density and radiation fluence, irradiated carbon temperature and angle of arrival of the ion beam on its surface. The results analysis showed that the final geometry of the surface of irradiated carbon materials is determined by reciprocal intensity of three processes: crystal structure defects formation, surface atoms spraying and growth of new surface formations. The latter can be result both of radiation stimulated surface diffusion and deposit or material from radiation created plasma component near the carbon surface. The results of this research work prove to a big extent the effectiveness of the use of radiation modifications of carbon materials and production of developed multi-tips cathodes on the basis of field electron emission. The report presents the measured emission properties of the field emission cathode, their utilization parameters stability and life-time at different current levels. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
