| Abstract | Thin films of high-thermal-resistivity electrical insulation were prepared by plasma polymerization of silazane and subsequent pyrolysis in air up to 1500 K of the deposited polymer. The chemical constitution of the films transforms into a silicon oxide type and a polycrystalline structure occurs after pyrolysis. The electrical properties of this material were intensively investigated. The symmetrical-Schottky-barrier model was proposed for description of the electrical conductivity. It has been found that above 400 K the thermionic emission mechanism dominates whereas at lower temperatures the transport is governed by the thermionic field emission. The deformation of the polycrystalline structure was observed upon application of an external electrical field. This process causes an increase of the conductivity. It is concluded that the thin coatings obtained by pyrolysis in air of plasma polymerized silazane films are characterized by strong adhesion to kanthal surfaces, high thermal resistivity, and very good insulating properties in a broad range of temperatures. |

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.
