| Abstract | The properties of sputter-deposited NbN thin films were studied under changes in various deposition conditions including nitrogen flow, substrate heating, the addition of carbon impurities, and the use of an Nb underlayer. Without the underlayer, a semiconductorlike resistive behavior above the superconducting transition temperature and a wide superconducting transition were observed in the niobium nitride films, including those with transition temperatures above 15 K. With the underlayer, metallic behavior and a sharp superconducting transition temperature depended strongly on nitrogen flow and substrate heating but weakly on carbon impurities. The authors present details on the preparation and analysis of niobium nitride thin films with and without a niobium underlayer as well as the measured film characteristics.< |

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.
