| Abstract | In this work, a new design of dual-gate source electrode (SE) dielectric-modulated tunnel field-effect transistor (TFET) biosensor with improved sensitivity and sensing speed has been presented. For this, P + (source) I (channel) N + (drain) type conventional TFETs structure is initially considered for comparison. Further to this, for the first time, an additional electrode is placed over the physically doped source region of the conventional biosensor with the negative supply voltage for extension of the cavity over the source region. The use of extra SE with negative supply voltage for the formation of cavity over the source region overcome the issues related to the formation of abrupt junction (at source/channel junction) and solubility limit of silicon material by the formation of a plasma layer of holes near to Si/HfO2 interface in the source region. Moreover, the presence of extra biomolecules in the source cavity region of the proposed device further increases the concentration of plasma layer of holes near to Si/HfO2 due to better coupling of SE and source region which is responsible for the improvement in sensing capability and sensing the speed of TFET biosensor. In this concern, a comparative investigation has been performed. |

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.
