| Abstract | Carbon Nanotube (CNT) is an excellent field emission source, and is widely explored in applications like sensors, AFM probes, cathodes for Carbon Nanotube Field Emission Display (CNT-FED), and cathodes for microwave device. The requirements on field emission characteristics for these applications vary, but it is often necessary to attach CNT onto a metal electrode surface. When CNT is grown directly on a metal surface by conventional CVD processes, the poor adhesion of CNT to the metal surface and, in some cases, low electrical conductivity leave room for improvements. We hot-bond CVD grown CNT with Ball Grid Array (BGA) of 0.5 mm diameter Tin alloy (Sn63/Pb37) spheres placed in pre-designated positions on a metal surface to form a cold cathode for microwave device applications. The forming temperature is about 200degC. This method not only provides an easy way to make CNT-metal cathode, it also greatly improve the field emission characteristics of the original CNT. The turn on electric field (at J= 1 $muA/cm^{2})$ is 1.56 V/mum with the field enhancement factor beta reaching 2203. The DeltaJ/DeltaE is around 1.09 M. |

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.
