| Abstract | Undoped and Ta-doped ZnSnO$_{3}$ thin films with different Ta concentrations were deposited on glass substrates by using sol–gel spin coating method. Effects of Ta concentration (0–4 at.%) on structure, surface morphology, electrical and optical properties were investigated. Single phase and crystallinity deterioration were observed in the XRD spectrum. The porosity rate was calculated by processed SEM figures with different dopant content. XPS spectrum and results of Hall measurement indicated that there might be substitution of Ta$^{5+}$ for Sn$^{4+}$ dominantly when doping content is lower than 2 at.% and main substitution of Ta$^{5+}$ for Zn$^{2+}$ when doping content is up to 2 at.%. A minimum resistivity of 1.716 Ω cm were obtained for films with 2 at.% Ta. The optical transmittances clearly exhibited absorption edges shift to longer wavelength, and those in the visible range increased up to over 91 % with increasing Ta concentration. The work function of undoped and 2 at.% ZnSnO$_{3}$ are 5.17 and 5.06 eV respectively, which are higher than ITO, FTO. |

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.
