| Abstract | Triarylium–solphonium salt, the chemical component of the SU-8 photo resist, has been proved as an effective n-doping source for graphene. In this reported work, a study has been made of the effects of SU-8 on single walled carbon nanotube networks. The results indicate that SU-8 behaves as an electrons donor and causes an upward shift in the Fermi level. The cross-linking property of the SU-8 resembles an efficient isolator from the oxygen of the ambient. This leads to ambient-stability of this doping technique. In addition, the doping technique shows negligible defects on the CNT surface and then higher transconductance is expected to be achieved. The temperature dependence of the Raman spectra of the CNT network observed a downshift in the G-band with increasing temperature. Finally, since SU-8 is an e-beam sensitive resist as well as a photo resist, it was used to selectively dope CNTs within the substrate area. |

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.
