| Abstract | Heterostructure backward diodes have been fabricated and characterized for use as zero-bias millimeter-wave detectors. Sensitive detector performance in the W-band was achieved by scaling the active area to 1.5/spl times/1.5 /spl mu/m/sup 2/ through the use of high-resolution i-line stepper lithography. Responsivities of 2450 V/W and 2341 V/W were measured on-wafer at 95 GHz and 110 GHz, respectively. The detectors exhibit good detection linearity, with 0.8 dB compression, measured at an RF power of 4 /spl mu/W at 95 GHz. A nonlinear device model, based on bias-dependent millimeter-wave S-parameter measurements, has been developed. The model is consistent with the measured frequency response, responsivity, and detector compression characteristics. Extrapolation using the model to reduced device dimensions suggests that this device technology should provide appreciable responsivities (>1000 V/W) at frequencies through G-band and beyond. |

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.
