Abstract | A novel metal-ferroelectric-insulator-silicon (MFIS) field-effect transistor (FET) with a Pt/Pb(Zr,Ti)O3 (PZT)/ ZrTiO4 (ZTO)/p-Si structure was fabricated and investigated for the first time. The PZT was formed by selectively nucleated lateral crystallization (SNLC), showing large rectangularlike grains (~40 μm) and smooth interface properties. An ultrathin ZTO layer showed a high dielectric constant (50), smooth interfaces in a ZTO/p-Si and PZT/ZTO layer, and an excellent interdiffusion barrier. From these material properties, the MFIS FET showed an excellent fatigue characteristic, which did not show any degradation in memory window (2.1 V), gate current density (10-8 A/μm), and fast P/E switching speed (500 ns) even after 1011 fatigue cycles. Furthermore, a long retention time, which only decreased 12.55% after 1 month and 26.97% after 10 years, was exhibited. |

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.
