| Abstract | Summary form only given. A self-consistent parallel plane model has been developed for fitting the nonlinear Fowler-Nordheim (FN) plots of field emission strips. The saturation behavior of field emission strips is investigated by using a finite-difference time-domain (FDTD) particle-in-cell (PIC) simulation. The field-emission process is described quantum mechanicallv by the Fovvler-Nordheim equation. Space-charge effects are automatically included in the FDTD PIC simulations. The simulation results have confirmed that the saturation is caused by the space charge effects. Within the framework of an effective work function approximation and energy conservation, the FN and Poisson's equations are solved self-consistently in the SCPP model. It is demonstrated that the nonlinear F-N plots of the field emission strips can be fitted by the SCPP model very well. The electric properties of the field emission strips can be characterized by the effective work function and the effective emission area. In addition, the field emission of Spindt-type cathodes may be possibly fitted with the SCPP model as well as the field emission strips. |

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.
