| Abstract | The impact of high-k dielectric pocket (DP) on the ambipolar conduction of tunnel field-effect transistors (TFETs) is demonstrated using two-dimensional Technology Computer Aided Design (TCAD) simulations. In the proposed structure of TFETs, an optimised portion of the upper drain region is replaced with a high-k DP at the channel–drain interface. It is demonstrated that due to the enhancement of the depleted drain region under DP, the minimum tunnelling width at channel–drain interface increases, and attains a maximum value for an optimum length and thickness of DP. Eventually, this increment in the minimum tunnelling width leads to a significant reduction in ambipolar conduction in TFETs. Furthermore, it is shown that performance parameters including the ON-state current, subthreshold swing and output characteristics are not affected by the presence of the proposed DP. Even, the gate-to-drain capacitance is reduced with the inclusion of DP at the channel–drain interface, thus leading to an improved cut-off frequency of TFETs. Moreover, it is also demonstrated that only a 10 nm of gate-on-drain overlapping along with this DP is capable of eliminating the ambipolarity completely for even a higher gate voltage of −0.8 V. |

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.
