| Abstract | It is known that carbon-related materials are suitable for field emission sources owing to its chemical and physical high stability and that some of them show superior field emission features; a very low threshold applied field and a high current density. In the case of emitter sources with an atomically sharp tip with a high aspect ratio such as carbon nanotubes, we have usually tried to explain the low threshold field by geometrical field enhancement. It has been reported, however, that even field emitters with no nano-protrusions sometimes give extremely low threshold applied fields [1, 2]. And it is noted that the FE features from carbon nanotubes have not been quantitatively confirmed to reproduce in the framework of Fowler-Nordheim (F-N) criterion because it is not possible to estimate the local electric field at the emission sites within classical electromagnetism in the case of atomically sharp tips. |

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.
