| Abstract | Summary form only given. Field assisted electron emission from nanostructured carbon materials is becoming increasingly attractive. The interest stems from the feasibility of diverse applications, which include field emission displays, electron-beam lithography, electron and ion guns, multitude of sensors, electron microscopes and microprobes, low & medium power microwave sources and lamps. Based on the present understanding of the carbon based field emitters, we may broadly define the requirements for field emission or the main factors influencing emission as a) field enhancement factor, b) highly conducting sp2bonded (pi bond) nanostructured carbon, in it's various manifestations c) the presence of $sp^{3}$ bonded (sigma bond) material in the $sp^{2}$ matrix and d) optimum emission site density distribution, taking into consideration factors such as shielding or overlapping of field, which could inhibit or limit emission. Taking into consideration the above, proposed is a novel, room temperature grown, self aligned carbon based multilayered electron emitter, suitable for most vacuum microelectronic applications. Discussed in this paper is a possible emission mechanism for such an electron emitter. Also presented is some of the experimental results of field assisted electron emission from such an electron emitter deposited on flexible substrates like polyamide. These emitters exhibit emission threshold fields, as low as 5-10 V/mum for a current density of 1 $muA/cm^{2}$ |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
