| Abstract | Application of keV-MeV ion implantation to perovskite oxides can be summarized in three different research topics: (1) to Induce controlled defects and dopants in High Tc Superconducting oxides (HTS); (2) modify electronic conductivity, ionic conductivity, and oxygen diffusivity in Solid Oxide Fuel Cell (SOFC) materials; and (3) modify the magnetoresistance prosperities in Colossal Magnetoresistance (CMR) oxides. Patterning the HTS films for HTS electronic devices fabrication is another well known application of ion implantation. This paper will mainly summarize and review the author work in topics (1) and (2). It should be noted that previous ion implantations into oxides were carried out at room temperature and the materials had been highly damaged or amorphitized. Even post-irradiation annealing will result in a more granular material than the initial material, leading to deterioration in material quality. It is observed that ion implantation of perovskite HTS thin films and oxide single crystals at elevated temperatures can induce dynamic annealing effects and crystal structure of the oxides can be maintained after the high dose implantation. Therefore, ion implantation at elevated temperatures provide an alternative route for modifying perovskite oxides. |

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.
