| Abstract | We report temperature distribution of graphene during Joule heating process using in-situ near-infrared (NIR) charge-coupled device (CCD) imaging system. Graphene layers were prepared using mechanical exfoliation of a pyrolytic graphite sheet (PGS), which is commercially available from an industrial materials company, and were then deposited on $SiO_{2}/Si$ substrates with approximately 780 nm thermally grown oxide. Thickness of the graphene layers was optically determined to be 20-80 nm using Fresnel theory. In order to investigate the heating process of the graphene, the temperature of the graphene under current flow was estimated using NIR microscopy with a CCD detector. A hand-made, in-situ experimental setup consists of an IR microscope, a NIR CCD, and an image enhancer. The CCD detector is mounted on the IR microscope with objective 20×. Heating experiments were carried out in obscurity. Joule heating process controlled with applied bias voltages was performed for the graphene in vacuum/ambient air, and the temperature distribution of the graphene during NIR emission was successfully studied by in-situ NIR CCD imaging system. The temperature of Joule-heated graphene was detected to be approximately 800 K. These results imply that NIR CCD imaging system is a useful tool for the investigation of temperature distribution of graphene. |

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.
