| Abstract | Summary form only given. Controlling carriers in diamond by doping is important to realize diamond electronic devices with advanced electrical characteristics. As a doping method the Plasma Immersion Ion Implantation (PIII) has been gathering attention due to its excellence in making shallow, highly doped regions over large areas, and its high dose rate, good dose controllability and isotropic doping properties. We have begun to investigate boron doping of diamond, silicon and diamond-like carbon films using PIII. As a doping source we use the plasma sputtering of a solid boron carbide (B/sub 4/C) target instead of toxic gas source like diborane (B/sub 2/H/sub 6/). The B/sub 4/C target of 1" diameter and a substrate (Si, diamond or diamond-like carbon film) are located in the downstream region of an ECR plasma produced by the microwave plasma disc reactor (MPDR) filled with 1-5 mTorr Ar gas. In order to sputter the target a negative self bias from -400 V to -700 V is induced by applying RF (13.56 MHz) power of 50-200 W to the target holder. For boron ion implantation, negative pulses of -1 kV to -8 kV, 1-5 /spl mu/s pulse duration, 1-200 Hz repetition rate are applied to the substrate holder using a high voltage pulser which consists of high voltage capacitors and MOSFETs. |

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.
