| Abstract | Controllable fabrication of nanostructure is important and necessary to application of nanomaterials in technology. Among the methods of fabrication of nanostructures, electron-beam-induced deposition (EBID) is a promising method. A transmission electron microscope (TEM), JEM-2010F operated at 200 kV, was used for fabrication of nanowires and nano-branched structures. Thin film samples Of SiO/sub 2/ or Al/sub 2/O/sub 3/ were used as substrates. Tungsten hexacarbonyl (W(CO)/sub 6/) powder was used as a precursor. The base pressure in column is lower than 2 /spl times/ 10/sup -5/ Pa. A gas introducing system which has a nozzle with an inner diameter smaller than 0. 1 mm and a reservoir of powder gas-source was used. The fabricated structures were characterized in-situ or after the fabrication with JEM-2010F TEM. All the experiments were performed at room temperature. Nanowires in diameter of about 3 nm nucleate on surface of substrate after starting the electron irradiation with intensity lower than 0.75 A/cm/sup 2/. They nucleate and grow within the all area electron beam irradiated. They grow almost normally to the surface of the substrate with distances of several nanometers between each other. |

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.
