| Abstract | We report the innovative development of a low-cost high dielectric constant polymer-based composite that combines the advantages of polymer-ceramic and polymer-metal systems for embedded capacitor application. This novel material uses low cost self-passivated aluminum particles as the filler for the polymer composites. The thin self-passivated Al/sub 2/O/sub 3/ layer forms a nanoscale insulating boundary outside of the metallic spheres, which has dramatic influence on the electrical behavior of the resulting composites. The nanoscale insulating oxide layer allows the aluminum composites to have a high dielectric constant as a percolation system; on the other hand, the insulating oxide layer confines the electrons within an aluminum particle, thus keeping a very low loss of the composites. Details of both particle and polymer materials are given in this paper. This study may have a broad impact since it reveals a category of new dielectric composites filled by metal with either self-passivated or coated insulating boundary layers. |

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.
