| Abstract | The present investigations show a new trend, introducing the possibility of forming superconductor/conductor/superconductor Josephson junction-like structure using MgB2 as a model for the superconducting species and layered graphene for the conducting species. The MgB2/Graphene/MgB2 junction was synthesized in three steps, firstly MgB2 was synthesized by a conventional solid state reaction in a nitrogenated sealed tantalum ampoule. Secondly, a chemical vapor deposition (ICVD) technique was applied to deposit a few layers of graphene on the surfaces of two identical smoothly polished pellets of MgB2 with the same diameter and thickness. Thirdly, the two pellets with deposited graphene layers were formulated into one pellet using a hydrostatic compressor at 4 Ton cm−2. The structural and nano-structural features of the resulting interference junction were investigated by Raman spectra, XRD, AFM/STM and SE-microscopy with EDX-analysis. It was concluded that the manufactured MgB2/Graphene/MgB2 junction was controlled by many parameters. |

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.
