| Abstract | Structure and electric properties of the sol–gel derived 0.45BiSc$_{1/2}$Fe$_{1/2}$O$_{3}$–0.55PbTiO$_{3}$ (BFS–PT) thin films deposited on Pt(111)/Ti/SiO$_{2}$/Si(100) substrates with LaNiO$_{3}$ buffer layers are investigated. Highly (100)-oriented BFS–PT thin films with thickness ranging from 200 to 600 nm were synthesized by introducing LaNiO$_{3}$ buffer layers. The as-deposited BFS–PT films showed enhanced dielectric and piezoelectric properties, the dielectric constant and effective piezoelectric coefficient $$d_{33}^{*}$$ was approximate 1820 and 110 pm/V respectively for film of 600 nm, which was comparable to that of BiScO$_{3}$–PbTiO$_{3}$ or PZT thin films. The thickness dependence of the dielectric, ferroelectric and piezoelectric properties was discussed. Besides, the direct current conduction mechanism of the films was investigated as well, indicating that bulk limited Poole–Frenkel emission was observed to dominate the leakage current in the high electric field. |

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.
