| Abstract | The DC and low frequency noise characteristics of InGaAs/InP planar separate absorption, grading, charge, and multiplication (SAGCM) avalanche photodiode are reported. These devices have DC gains greater than 100 with about 0.3 /spl mu/W input power and breakdown voltages V/sub br/ of 56 V. At 0.9 V/sub br/, the dark current is typically 10 nA for a 30-/spl mu/m-diameter active area device. The theoretical calculations of dark currents indicates that the primary dark currents come from generation-recombination and diffusion currents in both active and periphery regions. The breakdown voltage is in agreement with the calculation, which shows that the partial charge sheet does prevent the premature breakdown in the periphery region. The shot noise power is determined to be proportional to I/sup 2.7/, in agreement with theory. The lack of 1/f noise indicates the partial charge sheet is a good design to replace conventional guard ring design.< |

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.
