| Abstract | Summary form only given. The paper that we are going to present is about the characterization of field emission of a non-uniform distribution of emitters in a sphere-plane diode. In a recent article we showed that field emission in a non-uniform field can give information about the nonuniform distribution of emitters [1]. It can also explain the apparent non reproducibility of flat samples, which is a step toward standardization of field emission phenomena. In this follow-up paper we shall focus on an artificially generated non-uniform distribution that consists of various localized emission areas, much smaller than the diameter of the spherical anode. With our diode system we are scanning the anode over this area to verify our model of a single off-axis emitter. Applying a technique named Approach Curve Method (ACM) [2], for each position of the anode several I x V curves are generated as a function of the anode-sample distance (d). The V x d curves for a localized emitter distribution system enable a straightforward interpretation and will give information on the emitter position, the field enhancement factor (β) and the effective area of emission according to our model. |

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.
