| Abstract | Thin niobium-silicon multilayers have been sputtered with niobium thicknesses less than the coherence length and silicon thicknesses that allow tunneling between layers. The multilayer structure has been confirmed by X-ray diffraction, and the films have been electrically characterized with respect to T/sub c/ and J/sub c/. For constant Nb thickness, both T/sub c/ and J/sub c/ increase with decreasing Si thickness, indicating increased coupling between the Nb layers. When a multilayer forms the barrier in a tunnel structure, the resulting I(V) characteristic resembles that for a series of single-barrier junctions, and further evidence of Nb interlayer coupling is observed. These multilayers have also been incorporated as the base in several tunnel structures in order to measure the multilayer penetration depth via the magnetic field dependence of I/sub c/. Preliminary results indicate that the theoretically predicted enhancement of penetration depth in a multilayer does occur.< |

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.
