| Abstract | We propose a gate-controlled first principle approach based bio-molecular Nano p-i-n Field Effect Transistor (FET). Density Functional Theory conjugated with Non Equilibrium Green's Function has been applied to design this bio-molecular FET in atomic scale region. The device length is 19.618Å and this bio-molecular chain is made with two Adenine molecules and two Thymine molecules, which is attached with two electrodes made with Platinum and this device is wrapped with di-electric region and metallic cylindrical gate. This model has been activated in forward and reverse bias region, hence conducts satisfactory current in both n and p regions. Transmission spectrum, Device Density of States, Current-Voltage characteristics and Quantum Transport Co-efficients of this device has been analyzed. To achieve faster transmission the molecular device is passivated with Hydrogen atoms. The current-voltage characteristics model shows this device can act as bio-molecular n-channel and p-channel FET. Quantum Transport co-efficients like Peltier-co-efficients and Seebeck coefficients are calculated in this paper by solving Poisson's equations self consistent function method. In this model, opposite electrical charge doping procedure has been introduced in two electrodes which makes possible to create n and p regions at the two ends of the intrinsic bio-molecular chain. |

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.
