| Abstract | Low ON current and conduction for the negative gate-to-source voltage are the major drawbacks of the steep subthreshold slope tunnel field-effect transistor (TFET). Low work function on the source side of gate contact, high-κ gate dielectric and highly doped layer (delta doping) helps to enhance the ON current of the device. Whereas, low work function of gate electrode on the drain side and low-κ gate dielectric is used to eliminate the problem of conduction for the negative gate-to-source voltage. In the same concern, an analytical model for potential distribution of tri metal hetero gate dielectric delta doped TFET is developed by solving the two-dimensional (2D) Poisson's equation. Moreover, the extraction of electric field is performed by the developed potential model. However, model of drain current for the device is based on the Kane's band-to-band tunnelling generation rate. Finally, the verification of the developed model is performed with the 2D technology computer aided design ATLAS simulation results. |

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.
